Who's ready for the new incoming AMD CPU/GPU hardware?

[zanzabar]

Do you think it is a yield issue or a potential one for the 8 core CCX chips? Maybe they are trying hoard them for epyc?

6800xt 3ghz

[charged3800z24]

I like the 5800x i just think it's price point makes the 3900x a better value.

I get a better price from my supplier than retailers, so it was an easy buy for me. Paid $420.

I doubt that is even a thing tbh.

typically speaking the dies before they even make it onto a pcb are binned and of course they bin down so anything we get on desktop did not make the cut for enterprise.

It's rather simple, AMD is the performance leader now so they can charge whatever they want. If anything i'm not complaining about 5800x price its more like I feel like they just priced 5900/5950 to low and it's going to steal market share from 5800x. The gap between 6-8-12-16 isn't very linear price wise so much so that I see no room for the rumored 10 core variant ( big grain of salt there ).

Anyway to break it down

5600 $300
5800 $450 2 cores cost $150 more
5900 $550 4 cores cost $100 more
5950 $800 4 cores cost $250 more

Basically the cost per core makes 0 sense whatsoever.

What would make alot more sense is

5600 $300
5800 $400 2 cores cost $100 more
5900 $600 4 cores cost $200 more
5950 $800 4 cores cost $200 more

Making every core pricing linear and worth $50 per core to AMD.

Current pricing the only chip that makes sense to buy is the 5900 as it's the best value by far.

Current pricing the 5800x is the least value by far.

6800xt 3ghz

I was looking at the GPU-z Pixel fillrate.
The 6800 Xt is showing 288.0 Gpixel/s While a RTX 3090 shows 189.8Gpixel/s That card isn't anywhere near that near fast. it's 7% slower on 1920 x 1090 10% slower on 2560 x 1440 and 15% slower on 3840 x 2160, this is based of Techpowerup's review
how the hell is does it have 50% more fill rate and end up slower? That can't be the rite fill rate for the card if it's consistently slower on every metric, and that's with out RTRT on.

[chew*]

I dunno in reviews I read it won in many things at 1080 1440 lost @ 4k.

Hands on with it just fooling around in some games and it's not a best case scenario with a 9900K the 6800xt is pretty damn fast. I've commonly seen this particular card running at 2.4+ auto

Pixel fill rate is going to be raw math. The amd cards have always been drastically more powerful in raw power. They have been 1.5-2x more since they were both unified shaders.

I have to say launch public drivers this time around are so far for me bug free.

[zanzabar]

That is a nice looking build

Seems ok with out Raytracing.
it's a bit of conidium their in comparing to 2080 Ti which has less Overall Rasterization compared to RX 6800 XT But and First gen Raytracing like RX 6800 XT
Then trying to compare to RTX 30 series you got about the same Rasterization but second Gen Raytracing.
Looks like They just need more Ray accelerators on it over all ( techpower list 6800 Xt as having 60 ray accelerators when I'm pretty sure it has 72 ray accelerators) The Ray Accelerators seem to be part of the CU's

is that based of simple math only?
Or some kind unique code?

I concur. I like that case, but just isn't big enough for me lol

Just wish I could find a case with a fan hole or fan mount for a fan behind the motherboard.

I need some help to figure out my code 97. I installed my new crosshair viii last weekend everything was working. Played Apex legends for one hour all settings stock on my sig computer. After shutting down to have dinner with my family, my pc will not boot up shows code 97. I pulled out a msi 970 from my son's pc and it worked on my pc. Installed my Radeon VII in his black screen. Is there any way to get the said graphics card working again. It's less than a year old.

[chew*]

Here's an idea of how much power this card has and keep in mind it's on a rather outdated stock running 9900K platform. With those mins you can easily lock fps at 144/144hz and have a 100% consistent gaming experience with 0 screen tearing.

PS for reference the 5700/xt are in the 120's avg @ 1080P on the same system.

For AMD to calculate performance values you have; ROPs * clock speed for the pixel fill rate, texture fill rate is physical shaders (TMU) *clock speed, and flops are logical shaders*clock speed*2. They do not take into account IPC or efficiency.

Nvidia has changed their core structure a few times since they went to unified shaders, and they renamed their shader count to logical shaders like AMD does when they locked the clock ratio at 2x core frequency.

All depends on what happened to it. sometime you can send them in for repair and they will fix it for a fee. Most of the time if and when i ever killed a gpu it was all dead not half dead.

Ok so pretty simple
taken IPC deficiency, because scaling can't be prefect then putting it at about 60-65% of that pixel fill rate seem about right.

so what's the Nvidia Math that seems more accurate ? if you have any idea....

I've killed one card with a metal fan clip on the back of it over the gpu die area while it was plugged in :/
I might have killed another similarly, power supply didn't thoroughly dissipate it's charge after being unplugged. Battery to the board fell on it. landed in the same spot as the fan clip.


I'm disappoint in the, PC enthusiast, PC gamer's "PC master race" as whole lately just impatient and the unwilling to wait for stock to fill up, but ok with buying things as soon as they release.
people where ok with buying $1,200 RTX 2080 TI's when it's MSRP price was what $800 now they want to complain about it during a world wide a pandemic. after production was stopped for a few months.
All you have to do wait three months and not buy anything, stock volume will pick up by then.

They are the same thing now. In the past Nvidia had a shader clock instead of logical cores so you would multiply the shaders by the shader clock (not core clock.) The ROPs and TMU are the same math. The big change is that NV more physical shaders that can do less threads (not a great analogy but it helps) so amd is counting bulldozer style to get higher flops that games wont utilize. With amd RDNA has fixed some of it but only the main shader in a unit can do things like schedule out of order operations. AMD also has a bottleneck getting data between the ROPs and the shader clusters that Nvidia does not have. Since most games are made a favor NV due to their larger market share it make the IPC look bad for AMD. On properly coded/optimized games that make full use of asynchronous compute the bottleneck is much less.

I gave all the cpu's a quick run over the past couple days. No outliers imo. avg or below avg at best. I'll dig in more over next few days.

One of the things I am interested in testing is 5950x 16 cores smt off versus 5800x in games to see if there's any uplift to be had there.

I agree, I got lucky with my case and artic freezer II 280 and patiently waited till in stock and not scalper pricing but i'm fairly certain i just got lucky. Otherwise i wait. Me first usually comes with bugs....

what board are you using?

Have you checked out the curve optimizer?

yeah now it's luck because it's Fomo (fear of missing out) on everyone.

Nah I just tested manual vs auto and came to conclusion that amd is still better than us at ocing there chips on ambient, in fact even better than last time.

Shader clocks are linked to core clock on Nvidia now aren't they ? I remember the shader clock differences vs core.
lol I almost wanted to call it the bulldozer of gpu's expect it actually has a performance increase. Just not great Ray tracing yet, still waiting on that "Super Resolution" (the FOMO on DLSS is retarded along with this Raytracing FOMO)
So what's making the bottleneck on the ROP's ? I can't find anything on it the Architecture it's all about the CU's shaders and infinity cache and Ray Accelerators. I was thinking the scheduler would be the bottleneck there ?
I was thinking AMD could add more separate scheduler to both the ROP's and the Ray Accelerators. However waiting to synchronize all that could be a nightmare. Some sort of bypass to the Ray accelerators in the setup now seems more logical and quicker, maybe that's why it's out of order execution though too.

[zanzabar]

The scheduler works with the ROPs directly, and in the past the ROPs could not do out of order and had to be scheduled in clusters. One of the big reasons that AMD chips did not scale well when they got larger (vega/fiji) was the way the rops worked. It required too much latency so they were bad at high framerates. They had it detailed in the RDNA2 white paper. There was coverage but all I am finding now is about the rx6800 and not the rdna2 reveal.

Got a 3900X open box at Micro Center last month for $340. Not a great chip but stable at 4450/4300 CCD1/2 at 1.306v, 1900 FCLK 1.12v SoC with a 360mm MSI AIO. CCX0/1 are equal and CCX2/3 are equal, can't get 25 MHz higher on any of them. Runs like 4525 in single thread loads stock / with PBO on so OC was worth it, the ST performance is basically the same. I guess I could have tried RMA for not hitting boost at all but

Posted on reddit because I was bored and some people went nuts and called me an idiot / CPU murderer for using 1.3v so I just deleted the thread and moved on.

Still waiting on ASUS reference 6800XT to ship, ordered from ProVantage on 25th, no estimated ship date. Might end up trying to snag a 3070 or 3080 instead if I don't get a ship date soon.

Thank mate for the info I rma the radeon Vii and am still waiting for the for XFX to resolve the issue.
Well ordered a MSI Radeon RX 6900 XT today was lucky to get hold of one at alternate.de.
Can?t wait to get my hands on it My boy will get the Radeon VII if xfx repairs it.

the PBO for single core on 3000 is highly dependent on cooling solution and highly dependent on application. CB single for example don't expect miracles. even 32m pi don't expect miracles. 8m pi yes you can catch the speeds in Hardware info with the refresh speed set to the fastest setting and sometimes catch in in AOD.

With 5000 series chips you don't need voodoo magic to catch peak PBO clock speeds in monitoring programs. They are more than happy to boost to those speeds quite often.

I haven't spent a ton of time yet on the hardware but so far i see a trend with temps vs RT on off. example godfall/dirt 5 run RT and I'm seeing 80c avg where as in pure rasterization i see 74c avg temps.
