A10-6800K = 100W TDP

Athlon X4 845 = 65W TDP.

Energy consumption its not important for ShintaiDK suddenly :rolleyes:



How did you come to that conclusion ??

I know it doesn't matter to you. :)

What do you think a 4.1Ghz 65W Richland scores? ():)

Looks like the Cinebench R15 all cores score is OK unlike the previous benchmark. Looks like it was a motherboard bug IMHO.

Since 100W TDP A10-5800K 4.2GHz Turbo is slower than 65W TDP 3.8GHz Turbo Excavator, I find it very unlikely a 65W TDP Ritchland will be any faster than 100W TDP Trinity.

Not to mention that 65W TDP Excavator at 3.8GHz is faster at ST than 95W TDP 4GHz Steamroller.

Between Penryn and Nehalem IPC. Good job by XV team. It also makes XV the best improvement made over previous generation in the CON family.

According to the CPU-Z benchmarks posed by csbin, XV has roughly the ST perf/clock of a Sandy Bridge.

it turbos up to 3.8GHz for ST right?
my sandy bridge which turbos up to 3.2GHz scores nearly the same on CPUz ST, so not quite there

also the same up to 3.2GHz SB scores 1.27 on cb11.5 st


A10-6800K = 100W TDP

Athlon X4 845 = 65W TDP.

the TDP is also affected by the IGP on the A10.

My 2.3Ghz 6100U can reach that in CPU-Z. Just to show how silly it is. And so did my old i5 661 :)

My 4.455Ghz G4400 scores 2100 / 4000 for CPU-Z benchmark, in 1.75.0.

Edit: More accurately, I just ran the benchmark again, with other stuff running in the background, and I got 2261 / 3956.

Would be great to have a comparison of both at same clocks, doing not Cinebench but other tests on AT suite. Can someone call the OP there to get here?

Not in ST or MT Cinebench or any other CPU only workloads.

do you think they are constrained by a 65W TDP for a ST test like that?
do you think the 6800K is anywhere near 100W for that ST test!?

Yes and yes

Look at the score of A10-7700K 95W TDP 3.8GHz Turbo vs 45/55/65W TDP A8-7600 3.8GHz Turbo.

So if we add 40% to get the best case Zen ipc...?

At 65W TDP you just add 40% over the Athlon X4 845. But ZEN will come at 95W TDP as well, so ST performance will be a little higher.
Edit: Assuming same clocks as this Athlon X4 845.

But Cinebench is the worst case scenario for AMD CPUs both in ST and MT.

They didn't say performance, they said 40% higher IPC, clocks @ 65W/95W remain to be seen.

Why would CB still be a problem for Zen though?

Because ZEN arch is not the same as Intels arch. ZEN may perform better than Excavator but it will never utilize 100% of its capabilities running Cinebench.

I'm impressed by this. CPU-Z bench might be a pure integer workload, this might imply it would have very good desktop multithread performance. But FP is not what this arch good at, same as previous gen(BD,PD,SR)

Zen should be a big improvement over XV, so it should handle CB much better.

Hard to believe that it won't, and if it doesn't, it's not good.
