[Various] AMD’s Zen Eight Core CPU Delivers Double the Performance of the FX 8350 (Update 2) - Page 41

Piledriver: 1,8 cores * 1 FP IPC * 1 SMT * clock = 1,8 IPC per two cores
Zen: 2 cores * 1,5-1,6 FP IPC * 1,15 SMT * clock = 3,45-3,68 IPC per two cores

In floating point, when all threads are used, Zen should be twice as fast with the same amount of cores at a specific clock speed.


I was also forgetting about Zen's hyperthreading, its 8c/8t vs 8c/16t.

Yeah yeah, I'm not going to join ant hype train until i see a REAL review.

The FX-8350 / FX-8370 runs at 4.0GHz in MT workloads and up to 4.2GHz with ST workloads. There is no way 8C/16T Zeppelin can reach those clocks at 95W. It isn't even certain that the process or the design can hit clocks that high even when overclocked. Just look at the clocks and TDPs similar Intel chips are rated for. And that's on a significantly better process too.

If 8C/16T Zeppelin would be 2.8GHz base frequency (i.e MT workloads) it would be 40.35% faster than FX-8350 / FX-8370 (4.0GHz), not twice as fast wink.gif

This doesn't make any sense. TDP for the 8350 is 125W and Zen is 95W, supposedly. However, if you put the 8350 on a 14nm node instead of a 32nm, its TDP would be around 50 watts. Tell me again why there isn't headroom?

Also, Intel suffers from institutional Stockholm Syndrome stemming from their Netburst days as it relates to perf/watt. Frankly, they're entirely reliant on very conservative improvements in architecture or node to deliver mediocre performance and efficiency gains. If you asked an Intel engineer to deliver the sort of power savings AMD accomplished over the lifetime of the Construction series, they'd think you were crazy. If you asked them to deliver a 40% increase in IPC, they'd have a nervous breakdown.

It's a far wider design. More transistors take more power to run, but with so radical arch changes it's impossible to estimate whether there is or isn't any room there.

Sure, Intel could significantly improve IPC, it would be a huge core design with low max clock speeds. AMD has a lot more room to improve without making quite such hard compromises.

If Zen is as good as they say it would mean Intel will have to do something about it. I hope people dont go intel if Zen is as good. It does not help the market.

Absolutely, but nowhere near as wide as any of Intel's architectures. In fact, Intel has had exactly 4 architectures ever that were less than 16 wide. If you impose upon yourself an area limit (which you must) and a heat limit (which you must), and then you design a very wide architecture, you're going to be clock limited.

we are also keenly forgetting something here..

AMD chips dissipate much less power as heat per watt than Intel chips do, so comparing to Intel is kinda off regardless of width of Uarch

we are looking at potentially a new beast, this is tinfoilish but do ya wonder why BW-e is more espesnive than hw-e, earlier to market gains

they already made profit so they can dump prices and not lose as much once zen comes to market.

intel knows this chi[p will compete, and is bracing for it.

edit: i think my keyboard is dying...

Netburst was wide and deep, but it was a power hungry and hot monster as a result. The thing is, they're scared of making such a beast again, rather than shrugging their shoulders and using their hearts and minds advantage to get people to buy in. If Intel engineers are as great as some claim, surely they can revisit Tejas and get that under control?
