Nice find. Kaveri looks really promising.
What's with the huge loss on floating point?
Wasn't this guy making stuff up few months ago?
I don't know whether this leak is legit or not (though I'm shocked we haven't had more leaks if the NDA lift really is about a month off) -- but it makes sense. With AMD apparently going all-in APU, all their CPUs now have a huge coprocessor hanging off the side. It makes sense, and I've been expecting (and still expect them to, unless they change strategies) to start depreciating the FPU.
It makes a lot of sense. If you already have a huge GPU attached to your CPU that can be used for FP, and integer performance determines most consumer's experiences, dedicate your xtor budget to the integer pipeline, not the FPU.
As people have been noting for quite some time, there are issues with this strategy, but this is the strategy AMD has telegraphed for years. That doesn't of course, mean this leak is legit
Yup. "Simulated benchmarks". Not sure why anyone takes this joke of a blog seriously, it feels like it's written by Galego.
It is, isn't it. Wasn't that galego's blog that he kept pimping here before he was politely asked to vacate the premises?
Hah, that would explain it. Can we get this thread closed for being based on info from a banned member?

Sorry to burst your wishes of this thread being closed
because of your flawed assumptions...
So this shows there was no gain from bulldozer to Piledriver. Not convinced on the authenticity of the benchmark.
They link to http://news.mydrivers.com as source. news.mydrivers is just a copy and paste page. Your argumentation is flawed.
It can make sense if you have a fixed transistor budget and want to optimize your design for certain performance target points.It makes sense to stop investing in advancing the state of the art in your existing FPU microarchitecture...it doesn't make sense to actually invest money in developing an even lower performing one.
Seems that the supposed perfs are what make
some people wish that it s fake...

Intel cores have surpassed this kind of integer performance (per clock) for years now, and even with a 30% IPC boost it would still lag behind 2-year old Vishera FX6xxx (some models) and FX8xxx in many MT apps, dont forget there are only 2M/4C models. Not to mention FP performance got worse according to this leak and PD is pretty much equal to BD clock per clock. Yeah, sounds reliable.
