If you slim your OS with Nlite or something similar, it's not cheating, that's benching smart.

We compare our daily rigs together in a thread, well now that's the real deal right there!!! <----

Hey just because I can run DDR3 2800mhz Cas 12 on my Intel Rig doesn't mean my FX rig can. THIS is where tweaks come in.

_________

The difference from cheating and tweaking is the tweaking gains a usually pretty minimal. Diminishing returns in some cases. Cheating is usually pretty noticeable. HWBot governs this difference and pretty accurately. Most of the top guys out there have both run the cheats and tweaks for the understanding of and determination of the difference of the two.

@ "Usual Tweaking" -

A usual tweaker probably doesn't go out of the way to Nlite a windows XP OS for a pimod benchmark.

Usual benchmarking is a typical gamer that may submit his daily rig here and there to HWBot or not at all.

A Benchmarking individual will go out of the way to get a better score or faster time. I can tell you from experience that shaving 4 seconds Pi off your typical daily rig OS with tweaks and tricks is no easy task for PiMod, but can be done.

Had been addicted to Benchmarking. I have a special stack of special WXP and W7 installation disks. But none of these Operating systems have altered any benchmark in any way. They are stripped of a LOT of garbage you don't use for benchmarking.

So if I where really heavy into benchmarking with Blender or Blenchmark if you will, I would treat it no different than I would CatZilla, WPrime PiMod ect ect. I would try any tweak to get the best score. Even to beat an identical CPU at the exact same configuration.

I think competition would come to mind.

Let's compare our Blenchmark scores.

I agree completely with everything you said!

Like for me my daily rig is not clocked as high it can go ever. I like cooler temps on my water rig. But I could boost everything alot...

For people planning to build an AM4, will the motherboard support 32core Zen processors and are they completely unlocked as well as long as it's on the AM4 board ( locked on the server board? ) Their competitor locks all the multi socket processors.

For now the 8C16T Zen is going to be the highest SKU for AM4 and anything higher is going to run on AMD's new sever platform SP3 LGA IIRC. AMD usually does lock multipliers on non ES server CPUs.

AMD releases a small number of server Opteron on the desktop platforms as well.

AM3 was 1381/85/89 and is not considered AM3+ but runs the Phenom II core.

AM3+ was 3250/60/80 the 50 and 60 part numbers are HE. Opteron 3350/65 and 80 where also HE However I don't think there are any AM3+ PileDriver cores that I am aware of.

AM2/+ opterons ans s939 opterons as well.

So there may be a couple of Opterons that slip through on the AM4 socket as well.

So Zen only has AVX2, but will Zen+ have 3.1/3.2?

Some games benefit a lot from newer optimizations with the 4770K being 30% faster than the 3770K. It'd leave Sandybridge in the dust if more were optimized in the same way.

Zen has AVX2, but needs two cycles to execute a 256-bit AVX or AVX2 instruction.

The next version of AVX is AVX-512, which has been on Xeon Phi coprocessors now and will likely be in Cannonlake.

I haven't heard if Zen+ will feature AVX-512, but it would not surprise me if it did, and I would absolutely expect single instruction 256-bit AVX/AVX2.

Those results likely aren't part of any deliberate optimization, as even Serious Sam games that predate either part show a similar edge with Haswell and later architectures over prior ones.

Chances are that Serious Engine 3 just likes wide cores with fast caches. Haswell doubled L1/L2 cache bandwidth from Sandy/Ivy, which is why there is such a huge generational performance leap in some areas.

Yes AMD has released Opterons on it's desktop socket before but they never had a higher core count than the regular desktop flagship processor. It would be cool if they did release a 16C32T Opteron for AM4 but from what I have heard and read AM4 is a 95watt TDP socket so that is doubtful even at 14nm LPP. The 33XX Opterons were Piledriver core based, while the 32XX were Bulldozer core based.

Nice.

I always found the Opteron desktop series processors to seem more robust.
post #490 of 580
Maybe we will get a 6950X equivalent for sub $800-1000, looks like the performance is probably about equal clock to clock. For anything where a 4c/8t would do though it looks like Kaby Lake and then Cannon Lake is going to be where the fastest IPC is though. At least they are coming out with something good though and knowing AMD they always price things fair unlike Intel (at least enthusiast platforms). My hope will be though that they quickly roll out improvements over the next year or so increasing IPC by another 15% or something on their second round of chips or they will immediately fall behind again when Cannon Lake comes out. Hopefully they are much quicker about releases from here on out and keep rolling out improvements every 12-24 months.
