Some games are seriously lagging on Xeon E5-2690v2

[David is Back]

It seems to happen on map segments preloading. Can it bee because of my cheap SATA SSD, PCI-E 3.0 or because AMD GPUs (mine is RX 6660 XT) are screwed up for such games? Should I change my platform, if CS2 which I play most of the time is running fine, and my PC is more than OK in working tasks?

Also, what is the minimal and desired memory read speen value (from disk to GPU and from RAM to GPU) for modern games? I can test if mine is lower than needed

[Wichtelman]

did you run a benchmark software like userbenchmark oder passmark to check if your hardware works properly?

your xeon has a single core performance similiar to an i7-2600k and you provided no info about your internet connection or your ram etc

[_I_]

the 6600 xt only has 8 pci-e lanes, not 16
it needs pci-e 4.0 to be able to use all of its power

the xeon e5 5690v2 uses pci-e 3.0
so the gpu is choked by its bandwidth to the cpu

when it has all the data it needs it will run fine, but when loading new data its limited by the speed the board can deliver it and by the fewer lanes that it has

But multicore is much better. Also I overclocked my FSB to 114 MHz. CPUQueen test in AIDA shows score close to i7 11700K in stock (also read, write and copy from RAM scores are much higher than i5 10400F that I've been using for 2 months recently).


What exact tests do you mean?

And how can we fairly test the single-core CPU performance? I know that frequency is not everything, different architecture and so on, but still?

Thanks, so if I change my GPU to Nvidia 3060Ti or 3070 it will become better, or no guarantee?

testing whole system...

maybe your oc did screw your system aswell?

anyways check if all parts run properly and you would see how much pci-e 3 hinders your gpu

It doesn't seem like I have miners or viruses. And it is a fresh install, not a migrated one.

[It's Chase]

Well that's a 10 year old CPU, with really bad single core performance. The motherboard only has PCIE 3.0 too which will also bottleneck your GPU in games.

The best option is a whole CPU and motherboard upgrade.

[Illusion of Progress]

That's a very old and rather slow CPU now. It might have a lot of cores for its time but that doesn't matter for most games. The per core performance is pretty low, and that is what matters more for most games. You can't just look at a synthetic, best case scenario multi-threaded score and think you have gaming performance comparable to something else with a similar score. It doesn't work that way. It only takes one thread to become starved for a stutter to occur. "A system isonly as fast as the slowest link in the chain" comes to mind. It boosts a bit lower than many of the K variant Ivy Bridge consumer CPUs, which themselves are slow, and in modern games that do want more than 4 cores, it's also going to be slow because those games are also going to want not just more cores but faster cores.

In other words, it's just a slow CPU. It shouldn't be surprising if it might stutter in some games when even much more powerful CPUs and systems might stutter in some games. Game optimization isn't always great these days, either. Gamers flock to the newest unoptimized stuff time and time again (and never learn) so companies have developed schedules to push unfinished stuff out the door and maybe fix it later. That's certainly not helping, but the CPU itself is just old and slow now.

I agree with this. You need to maximize your platform. Putting a pice 4.0 capable GPU in a pcie 3.0 compliant system will introduce a perfect loss. The reason is the pcie lane operations only being 8 lanes at 3.0 speed.

That GPU supports 4.0 speed so you're only at half bandwidth. You're 8 lanes at 3.0 speed.

pcie 3.0 = 8 gt/sec

pcie 4.0 = 16 gt/sec

they are very close performing gpus, but the 3060ti has all 16 lanes available
at pci-e 3.0 it will have twice the bandwidth as the 6600xt


the 6600xt is kinda a useless card
bad combo with pci-e 3.0 mobos/cpus, since its limited on lanes, and on newer cpus it will be the bottleneck

3060ti has best of both worlds, all 16 lanes and pci-e 4.0


but the xeons are not really good choice for gaming
many cores, but very slow core performance
10 cores with ht, but only 3.6ghz

No garuntee.

TBH though _I_ is not technically wrong he is making a mountain outta a mole hill. Speaking as someone who has tested an x4 GPU (6500xt) on a PCIe 2.0 interface (i7-2700k). He is making too big a deal.

Your 6600/6650xt wont be saturating a PCIe 3.0 x8 buss any time soon, especially for regular gaming. Any differences in switching to a 3060 or 3070 would be down to the GPU and not to the PCIe.

it is choked by pci-e 3.0, there are many reviews on it

more or less depends on the game, constantly loading stuff will make it stutter more

Proof that the gen3 is a straw man and or baseless argument on the 6600xt.

omg, gotta quote this so it doesnt disapear or get eddited...

Did you even take the time to watch or check your own source?


Because I dont think you did. If you had you would have seen that each test was basically the same or within margin of error. The only game that showed any noticable (sub-10 fps) difference was Forza...

lol
