*** AMD "Zen" thread (inc AM4/APU discussion) ***

Just need Apple to start supporting AMD CPUs and I can happily move back to AMD. This generation look very promising.

Wonder how much further they can push it.
 
MT scaling looks epic according to the leaks, so "Haswell IPC" (it's a nebulous term, application dependent) is pretty nice really, especially given the core/thread/touted price

Anyone else see the firestrike CPU multiplier at 39x

So that's the score it gets at 3900Mhz? Pretty great, as the 5960x gets 19998 when clocked at 4.4ghz (source) and 16433 at stock clocks (3.5Ghz). So the scores aren't linear (25% increase in clockspeed only results in a 22% increase, which means you only have to multiply the % in clockspeed by 0.88). This means the 5960x at 3.9Ghz ((0.4/3.5*0.88+1) * 16433 => 18085.69), would score about 18k.

Looking at single thread to multi-thread scores, it does seem to support the idea that SMT is ahead of HT. If so then WOW!

Or it could mean they've enabled the dynamic overclocking feature, and one cannot trust these scores at all (firestrike running at 39x says a lot).
 
One thing that to me personally points towards Zen being a great out of the box Chip but not so great an Overclockers Chip is the fact there is no hype on these boards from Gibbo / 8Pack, infact i would go as far to say as 8Pack is probably not even interested in Zen.

While Gibbo has said they will do bundles, 8Pack has said they wont be binning AMD chips, this is probably due to Soldered IHS and the chips are probably near thermal limits / design limits that prevent massive gains via OC'ing. So no need to waste time binning chips that have been effectively binned by AMD already and are not really going to differ much between them in their brackets.

Thats my theory on things, im probably massively wrong, but i have read a few rumors that point at the chips not being so good at being pushed further, but the out of the box performance is good enough that you dont need to really look for more anyhow.

The upside to this is the iterations of Zen should be even better, there must be a lot of low hanging fruit that can be picked as they mature.
 
Right, so 5% faster than a 6900K in Firestrike Physics. https://forums.overclockers.co.uk/t...pu-discussion.18665505/page-346#post-30524962

Single threaded in Cinebench is = to Haswell / Devils Canyon but seems to scale better than Intel in MT so in that actually end's up scoring as high as Skylake 6900K. https://forums.overclockers.co.uk/t...pu-discussion.18665505/page-346#post-30524964

So at worst its as good as Haswell / Devils Canyon, at best its better than Skylake.

One weeks to go.....
