[AMD] Breakthrough Performance of “Zen” (Head to Head with Broadwell-E!) - Page 26

post #251 of 580
I hope this is decent. I want to build an AMD rig. Its been years since I could. So looking forward to this release and hoping its not a disappointment. cigar.gif

Anything at 10-15% near 6900k or closer on average and forget about aggressive pricing

8C/16T unlocked, 140W TDP
3.2ghz base clock
3.4ghz full turbo
3.8ghz 1core turbo
Price: 800E++++

8C/16T unlocked, 95W TDP
2.8ghz base
3.2ghz full turbo
3.6ghz 1core turbo
Price: 500E+

8C/16T locked, 95-120W TDP
3Ghz base
3.2 full turbo
3.8 1core turbo
Price: between the 2 above

Expect 6cores at 300-500 and 4cores at 150-300.
If zen is a failure (according to the expectations that amd set, with the blender benchmark), like 20% slower than 6900k or more on average just divide all prices by 2

I think they will price it 20-25% cheeper for 8c 16t, and wont be under $500. And $200-300 for bristol ridge 4c 8t. Maybe cheeper bc they will use fd soi for bristol ridge.

Im expecting not less than haswell with lower pricer. If so ill upgrade to zen or just go with skylake/mr crab. Wont hold my breath tough, but ill hold till zen show its face biggrin.gif

Just want to point out that IPC is not a limiting factor in Workd of Warcraft, that's the APIs Drawcall support, they really need to implement DX12 in that game.

CPU performance and workload efficiency are both performance multipliers. 50% more IPC does give 50% more FPS in WoW. Halving the CPU workload would also double the FPS if you could do it, of course

What I mean is that even with my i7 4790K @ 4.8GHz I still drop to 20 FPS on my GTX 1070 when doing several WPvP raids, although with the latest patch Blizzard implemented a system that reduces the amount of effects shown in raids, it still doesn't help the fact that no matter the IPC you're still dropping to sub 20 FPS WPvP scenarios where several raids are clashing.

That is a huge drawcall bottleneck.

But bottlenecks only happen with AMD cpus...... tongue.gif lol

Once you look at benchmarking results like super PI. AMD is so slow they have to have their category. Sorry not buying into the hype.

Super PI, the Intel shills go to benchmark for when new AMD cpus are close to release. Bulldozer has to emulate the instruction set because it's no longer supported...

I have around double that performance at the worst that i've managed to hunt down. There's a performance bug with shadows in WoW, you'll see FPS increase by 50-300% if you set shadows to the lowest setting compared to the next setting up - you may be experiencing that issue.

Anything significantly limited by one component more than others is bottlenecked by definition.

Here's one of the lowest performing benchmarks i've taken in WoW with Skylake:



You see the point where the boss dies and FPS flies way up. After that i move away from the blob of people and FPS goes over 160 to become GPU limited again.

Where i have 40fps my friend with a stock bulldozer CPU has 11fps so of course it matters. Like i said, both CPU performance and CPU load applied are performance multipliers. If they halved the CPU load of the game in that situation then he'd have 22fps and i've have 80fps!

Is your friend using an MSI motherboard? I've begun to notice a trend that some AMD motherboards offer extremely low performance and swapping to a different brand can offer very large increases. MSI has been one of the largest offenders.

My 980 was at something like 15% load and he has a 290.

Nop - and that's not very unusual performance for the situation. Stock bulldozer has very low ST performance, bad memory/cache performance etc, it has no chance of even being in the same league as overclocked skylake. There's also the drop in performance for using AMD's graphics driver as they take a lot more CPU per frame than Nvidia's does which has a significant impact on results.
