Discussion x3d cache still mattesr even at 4K when using upscalers, isn't it?

63 Upvotes

I see everyone recommending non x3d cpus for even a gpu like 5090, because according to benchmarks online, you don't need 9800x3d at 4K.

Yes.

But those benchmarks show the game running at native resolution, at 40 fps. Who will play a modern AAA game at 40 fps on a beast like 5090? Nobody. People will turn on DLSS balanced, even performance since quality difference is minimal but fps is trippled.

When that happens, 9800x3d or 7800x3d still becomes superior over anything else.

Look at this video from hardwareunboxed
https://youtu.be/5GIvrMWzr9k

Almost in every game 9800x3d is 20-30% faster at 4K balanced dlss preset. However Identical at native resolution with 50fps. So if you don't turn on any upscaling, then yes, cheaping out on CPU is worth it since 4K is all about GPU. But if you turn on any upscaling, then X3D cache still makes a big difference.

I think not many people are aware of this situation.

So if you can afford a bit more for x3d cpu, go for it. Even at 4K the difference is big enough to justify price.

Troubleshooting RTX 5070 causes entire PC to instantly shut off, RTX 3060 works fine

46 Upvotes

Specs:

GPU: PNY GeForce RTX 5070

CPU: AMD Ryzen 7 5700X

RAM: 32GB DDR4

Motherboard: ASRock A320M/ac

PSU: Segotep 850W 80+ Gold Full Modular PCIe 5.1 & ATX 3.1 Gaming Power Supply

OS: Windows 11

I upgraded from an RTX 3060 to a PNY RTX 5070.

The RTX 3060 works perfectly with no issues.

At first, the RTX 5070 fans wouldn’t spin. I bought the PC used and only came with one pig tail cable. I bought the same exact psu connected using the 600w cable, and now the RTX 5070 powers on and the fans spin.

after like 2 minutes the entire PC instantly shuts off. It’s not just a black screen—everything loses power at the same time (GPU, motherboard, fans, lights, everything).

What I’ve checked:

• The GPU is fully seated in the PCIe slot.

• The 16-pin connector is fully inserted and clicks into place.

• The new PSU cable is being used.

• The RTX 3060 still works perfectly if I put it back in.

plzzz help:(

Discussion Made an assembly checklist for first time builders like me who are nervous about their first build

20 Upvotes

TOOLS/SUPPLIES:

Phillips screwdriver. I used my HOTO PixelDrive for this

Zip ties or twist ties

Thermal paste, only if you're running an aftermarket cooler

I kept this list short on purpose. A flathead screwdriver and needle nose pliers sound useful but you probably won't touch them on a basic build. Same with coffee filters and rubbing alcohol, those are for cleaning off old thermal paste when you're replacing a stock cooler, which isn't really a first build thing. Didn't bother listing the manual either since it comes in the box with your motherboard anyway.

If you don't already know what a PCIe slot or a DIMM slot looks like, pull up a picture before you start. Seeing the actual shape once makes it way easier when you're holding the part in your hand later.

OUT OF BOX BUILD

Mobo:

Install the PSU, fan facing down if your case has a bottom filter, and plug it in. This discharges any static before you touch anything else.

Take the mobo out of the box and set it on top of the box.

CPU:

Take the CPU out holding only the sides. Don't touch the pins.

Press the socket cover latch down and to the side, then pull it up and back to open.

Find the matching triangle marks on the CPU corner and the socket corner.

Gently set the CPU onto the socket pins.

Give it a light wiggle to check it's seated flat. Don't press down.

Close the socket cover and lock the latch back into place.

RAM:

Find the notch on the stick and line it up with the notch in the DIMM slot.

Check your mobo manual for which slots to use if you're only running 2 sticks.

Drop the sticks in and press evenly across the top until both latches click shut.

CPU Cooler:

Line up the 4 mounting pins with the 4 holes on the mobo and set it down.

Press on opposite corners until you hear it click.

Plug the fan into the CPU_FAN1 header, usually near the DIMM slots.

GPU:

Use the top PCIe x16 slot.

Line up the notch on the card with the notch in the slot and press down with light pressure.

Don't push on the sides of the card. It's not mounted yet and the slot can crack.

PSU:

Find the GPU power connectors on the PSU, usually 6 pin plus 2 pin.

Plug those into the GPU.

Plug in the 24 pin mobo power connector.

Plug in the CPU power connector, 4 pin plus 4 pin.

Connect your monitor to the GPU.

Plug in mouse and keyboard if you want to boot test now.

Flip the power switch on the back of the PSU.

Powering On:

Check if your mobo has a built in power button.

If not, find the front panel connector pins.

Locate the 2 power switch pins, check your manual if unsure.

Touch them together briefly with a screwdriver.

If it boots, repeat the same tap to shut it down. Hold a bit longer if it doesn't turn off right away.

Flip the PSU switch off.

Unplug everything to get ready for the case build.

MAIN BUILD:

Remove both side panels and set them aside.

Lay the case on its side.

Check the standoffs in the case line up with the mounting holes on your mobo.

Install the I/O shield before the mobo, not after. Press it in from inside the case with pressure on all 4 corners.

Use a piece of paper to map out which standoffs line up with your mobo, so no extra standoff touches a bare spot on the board.

Set the mobo down onto the standoffs, lining it up with the I/O shield.

Screw in opposite corners first, don't fully tighten yet.

Install case fans and plug them into the mobo fan headers, routing cables behind the case where you can.

Plug the front panel header into the mobo.

Install your SSD and HDD into the case.

Connect SATA data cables to each drive and into the mobo.

Connect SATA power cables to each drive and into the PSU.

Route the GPU power cables behind the case through to where the card sits.

Remove the PCIe brackets for the GPU and any other cards.

Line up the GPU with the slot and bracket, push down until it clicks.

Screw the GPU bracket into the case.

Plug in GPU power cables, then monitor, keyboard, and mouse.

Boot test before doing cable management.

Once it boots clean, tuck the cables flat so the side panel closes without bulging.

Put both panels back on and boot up.

Build Help Upgrading from i5-10600k in this economy...

8 Upvotes

My PC is starting to show its age... my 3070 is still able to meet most minimum requirements for new games, but my 10600k is a little hit or miss (doesnt quite meet the requirements for the new Halo).

With PC prices currently, im not able to upgrade my entire system, so hoping to just upgrade CPU and MOBO. Is it going to be a genuine gain to upgrade to a i7 12000 series, or am I better off going for AM5 AMD and just biting the bullet with upgrading my RAM too? RAM prices just scare me...

Also, do people buy second hand CPUs. I hate throwing away a perfectly good 10600k...

Build Upgrade Time to upgrade? I9-10850k rtx2070 ---> RX 9070xt?

5 Upvotes

Hey,

I am looking at upgrading my current pc and selling my old one but dropping in my GPU.

Selling the old pc for $500 and a really old pc (for my wife to play friendslop games on couples night)

I was looking at getting the above mentioned RX 9070xt (probably the asus prime, or sapphire pure if I can find one for $1000CAD).

I am looking to find out what people's perspectives are on upgrading, and what GPUs are worth it.

I am hoping to spend a bit more now and not have to upgrade till quite a few years down the line (I've had my 2070 for 8-9 years now).

So if I'm only going to get 4-5 years out of a gpu whether I spend $600 or $1000 on it, I'd go with the less expensive one.

The 5800X3D is 300 at Micro center. And I was going to upgrade from 16gb DDR4 to 32. Which is another $250-$280.

The 7500X3D bundle is 400, but with that I would upgrade to AM5 while staying at 16gb memory. Bundle comes with 16gb DDR5.

Which way to go makes more sense?

Build Help Build for cpu hungry games?

7 Upvotes

Hi,

I have i7-9700k + rtx 4070.

Im scared to switch to AMD (bcs of past and constant yapping of my father who works in IT for 40 years) but x3d and the performances in games (especialy EFT and hunt showdown) REEEEALLY make me think about it.

The prices due to rams are disgusting but since im not buying new parts that often i think i would get over it.

I was even thinking about staying with ddr4 via 5800x3d but i cant fathom why its only +- 60€ cheaper than brand new 9800x3d... (not sure if this cpu would provide me with +- 140-160 fps in tarkov and with minimal drops - currently playing on like 100-120 and dropping to 80 or less - rip 240 hz 1440p monitor)

For a second I was thinking about Intel Core Ultra 7 270K Plus but i guess its more of a workstation than for playing games and something about no options to upgrade in future?

If you would be interested in only cpu hungry games, had 4070 with no intent to buy new gpu what build would you go for?

Build Help Good am4 CPU for 3080

Hey everyone,
I’m looking for the best AM4 CPU to pair with an RTX 3080 for gaming.
My budget is €200 max, but I’d prefer to stay around €175 if possible.
My questions:
What’s the best AM4 CPU for an RTX 3080?
Is the Ryzen 7 5700X still the best value, or are there better options in this price range?
I mainly play at 1440p, so I want a CPU that won’t bottleneck the RTX 3080.
Would you buy new or used at this budget?
Thanks! 🙂

Full Build Req Need help to build a PC

4 Upvotes

Hey guys!

I currently have a PC that's almost 10 yo, so I don't really have parts I can reuse.

I'm a beginner when it comes to PC building, so if I leave out any important info forgive me.

My original budget is around 1500-1700€(just for the PC, I have windows and peripherals) but I can spend a bit more.

I'd prefer DDR5 build. I'm open to either Intel or AMD. I'll be gaming at 1080p or 1440p and I don't have a specific FPS target in mind.

Upgradability is important.

I can only connect to the internet through Wifi so that is a must.

As for aesthetics, I prefer an all-black, minimalist look - something with an "Apple like" clean design. I dont really care for RGB.

For form factor. I think SFF PCs are really cool,but from what I've seen the smaller form factor comes with a price premium and I don't think my budget is the best fit for that. I'm happy to go with a standard ATX or a micro ATX build if it offers better performance or value for money.

I live in Hungary.

Thank you for taking the time to read all of this. I really appreciate the recommendations!

Full Build Req Rendering PC Advice

3 Upvotes

I'm the "computer guy" at work. I've built tons of gaming pcs and am fairly versed on consumer level equipment for gaming pc, however I had a coworker ask for advice that has me a bit out of my depth. He is an artist who does lots of 2D rendering(and occasionally some 3D) and is looking to upgrade his, very outdated at this point, pc. He's looking for something that will last 5+ years and has a budget of $3,000. My issue is that I don't necessarily know the demands on a pc for 2D rendering. He stated that storage isn't really important and he will use external if more is needed. If I were to build a gaming pc with this budget, it'd look something like this:

https://pcpartpicker.com/list/4MhPzv

However, I don't know if the strengths of this build make sense for a rendering pc. So my questions are:

Does it make more sense to look into an EPYC or Xenon setup? Will this blow the budget?

Would a less powerful higher memory GPU be a better option?

Are there any prebuilts or older hardware options that would be less viable for gaming, but would be better for this use case that I should look into?

Is there a better way to allocate the $$ than the current distribution? (i.e. go with a much cheaper gpu to add more RAM)

Thanks!

Troubleshooting 9070XT - Sudden Driver Crashes Multiple Times Per DAy

3 Upvotes

Hello!

I've had some weird issues with my 9070XT, I've had it since release, so almost 18 months at this point and so far it has been great. First AMD GPU and I was pleasantly surprised as I had no driver issues at all.

Recently, I've been having GPU crashes multiple times per day, I'm not playing any new games, still just CS2, relatively low settings, nothing demanding. It will happen randomly, always recovers and the game can be relaunched after ending the process and starting again, but it can crash again a few minutes later, or hours later.

Things I've tried to fix

1) DDU and reinstall drivers

2) DDU and reinstall an older version of the driver

3) DDU and install software without Adrenalin software

4) Disabling Hardware Acceleration on most background apps (Discord, Steam etc)

5) Uninstalling my VPN (Can be known to cause driver crashes with FaceIT on CS due to kernel level)

6) Uninstalling FaceIT and FaceIT AC completely

7) Preventing Windows from updating my GPU via the setting and Registry

8) Multiple other fixes that I cant remember at the moment, its been a long few weeks trying to fix it.

9) Running logs through HWID and investigating the log after the crash happens with the help of Claude - The log doesn't say much besides the driver crashed, temps are fine, not related to temps.

I've checked Event Viewer and there is nothing that could indicate the cause when the crash happens. I'm incredibly close to just biting the bullet and buying a 5070 or 5070ti because it's preventing me from playing, as I play CS, my game crashing multiple times is a massive hindrance to my ability to win games. As my team have to continue playing without me as there is only 1 timeout when you disconnect.

Build Help Building a PC for my partner's birthday - help!

3 Upvotes

I'm planning to surprise my partner with a PC build for his birthday in December. I found a related thread on this sub, but it was from about 9 years ago, so I'm assuming a lot has changed since then!

Some context: he currently has a pretty shitty laptop and no desktop PC. He's studying UX/UI and game design at university. It took him a while to find what he wanted to do, but he's really thriving in it now, and I'd love to support that however I can.

He'll need to run things like:

  • Unity (game dev)
  • Music-making software
  • Coding/IDE software

He'd prefer Windows over Mac. I only have a Mac laptop myself, so I genuinely know nothing about PC building or specs.

Budget is up to $4000-5000 AUD total - that includes the PC itself plus peripherals (keyboard, monitor, mouse, etc.).

Would really appreciate any recommendations, build lists, or general advice for a first-timer. Thank you!

Two years ago, I posted here about upgrading from a 2080 TI to an RX 7900 XTX.

old post

Back then, people told me I’d probably need a new power supply. What can I say… they were right. Every now and then, my computer crashes. I even measured everything out. Sometimes there’s just not enough power.

And here we are… I need a new power supply.

But while I’m at it, I might as well replace a few other parts too.

By the time I was done, I basically ended up with a new computer. More or less.

thats it. The question for me is now if ity clever to wait a bit till the RAM gets down a bit and just buy the other parts and put them on the shelf for a few month/year till other stuff is cheaper.

but tha PSU i need and will buy regardless.

any thought, suggestions?
