does he use ddr4 with the 12900k? why else would it perform worse in his benchmarks than techpowerup
I went from the i5 10400f, and it still felt like a console gen bump up. I have it paired with the Rx 7900 xtx rn and it’s amazing!
My 2600X is definitely starting to show its age, looking to upgrade to the 5800X3D this BF along with a new SN850X, should speed things up nicely I hope.
5800X3D is still a great CPU for anyone on AM4. Will certainly be a huge upgrade over what you’ve got.
I think the 7800/7950X3D is a big leap from the 5800X3D. 2700x to 7800X3D probably feels like a console generation jump.
if that feels like a console gen jump then going from my cur
the jump from 2700x and 5800x3d is easily a generational leap
yeah the 7000 series 3d chips are easily a multi gen equivalent upgrade over the 5000 3d chips, and i say this as a 5800x3d owner. unleashing the full power of extra cache and the full ipc of these chips is jsut awesome. hopefully next 3d chips have even more cache.
2700x to 7800X3D probably feels like a console generation jump.
probably more than that honestly.
I had the 8700k from those times till this year and it was a mind blowingly significant upgrade. A lot of vr titles were unplayable for me because of steamvr overhead(it’s really crap when you use non valve headsets). F1 23 went from a stutter fest to locked 90.
Although in case of f1, the devs were at fault too because the game is broken with extreme stutter unless you can lock to the refresh rate
Steamvr isn’t causing your stuttering.
It does. There’s a reason opencomposite is so widely adopted on wmr, pimax and oculus headsets. Using steamvr with wmr for example, the shim layer copies the framebuffer and causes a large increase in vram usage as well as cpu usage.
Although in particular case of f1 23 the game itself also causes issues outside of locked refresh rate
I’m so annoyed I let some friends that I thought were a little more knowledgeable talk me out of going AM5 a few weeks ago. Went from 3900X to 5800X3D in an unplanned upgrade because of bottlenecking with a 4090. Everybody told me don’t go AM5 yet, it’s not ready, and this first round isn’t a big enough jump to justify the new board and RAM.
Now I sit here with an awesome machine that could have been awesomer for about €200 more and I’m really considering swapping up using the proceeds from selling off the 3900X/2080ti.
Actually I was surprised to see the 5800x3d in the top half/quarter of most of the charts.
Yeah but 2700X to 5800X(3D) can be done on the same motherboard with the same RAM!
The incremental cost of the 7xxx series is a lot larger.
The incremental cost of the 7xxx series is a lot larger.
the incremental cost of not buying RAM now while it’s cheap is going to be a lot larger too.
how long do you really want to be using that shitty 2018-era 16GB kit? are you comfortable riding it for another 2-3 years until RAM prices finally come down again?
people are about to learn a hard lesson about buying things when they are cheap. RAM prices in 2017 were triple what they were in 2016 (and not shitty kits either, by that point it was 3000C15/3200C16 kinda stuff).
and before too long the 5700x3d will be an even cheaper upgrade for those still on am4
5800x3d ruined 7000x3d sales I guess
5800x3d has issues with usb drops out and 7800x3d has issues with stability. neither are worth their headaches.
I’m not sure the 5800x3d itself is really to blame… I had big usb problems with mine (and a 3900X) on one upper-mid-range x470 board, but when I upgraded to a top-end x570 mobo, my usb issues went away. Yeah, a somewhat pricy solution, though I got it for a decent sale price at least. (Oddly the 3900X on that x470 mobo has been running with few to no problems as a secondary Linux machine.)
no usb dropout problems here, two cheap b450 boards and a zen 2 and two zen 3 cpus
outside of a few games, my 2700 holds up well. Too bad it’s effin slow with TrueNAS.
How is it slow with TrueNAS?
Is there a reason why the 7800X3D beats the 7950X3D when it’s meant to be clocked lower? Is it a scheduling issue or something where the wrong cores are used? If CCX1 was disabled would the 7950X3D then become consistently better?
The reason why the Ryzen 7 7800X3D is able to perform as well as the flagship comes down to the fact that it uses a single core complex (CCX). That leads to faster cache-to-cache transfers, according to AMD, helping the Ryzen 7 close the gap in gaming performance compared to the dual CCX Ryzen 9 7950X3D
The early reviews showed the 7800X3D a little faster than the 7950X3D, but the scheduling has been improved since then. The 7950X3D is faster for gaming in most cases now, because of the slightly higher turbo.
Nothing has changed about 7950X3D scheduling since launch.
It’s just a matter of how many games are included in the average where the gamebar parking doesn’t work.
It also depends on whether they’re evaluating games that use more than 8 cores. The 2 CCD latency penalty is probably a little bit overblown because even in the previous generations, 5950X/5900X beat the 5800X in quite a few games.
Is it a scheduling issue or something
Yes. Hence the Intel’s release of a scheduling driver for 14th gen.
