Thanks for the contribution man! What a helpful member you are.

Thanks smile.gif

It was all explained to Usario via PM smile.gif

Need some user or review site to look at this /shrug not 100% on the math. Needs to be tests; I don't have a high end card to go about testing it

yes, you are right ! According to your calculation, It would obviously allow data to be transferred at speed required by PCIe 3.0 class GPU.
But unfortunately it will still be a bottleneck, because GPU is still limited by PCIe 2.0 x16 slot where maximum unidirectional bandwidth is only 8 GB/s. Hence increasing HT will not be of any worth. redface.gif

However I've tested my friend's ( xt-107 here on OCN ) GTX 670 on my system. Sandra GPU Video Memory benchmark shows his Intel SB-E based system can push data from GPU to CPU at a rate of 11GB/s but my Phenom II (CPU-NB at 3000MHz ) + 990FX ( HT at 3000MHz ) can transfer at only 5 GB/s. This clearly proves his SB-E platform can transfer data at 120% faster than my system.

Yes we did many real world gaming at his full HD 120Hz monitor (Crysis, Warhead, 2 and 3 Alpha online, Battlefield 3 campaign and online, Sleeping Dog, Apache Air Assault, Darksiders II, Prototype 2, Resident Evil 5, NFS Shift 2, Metro 2033, GTA IV ) and good thing is that smile.gif most of time my Phenom II CPU at 3.5 GHz - 3.7 GHz was pushing his GTX 670 to almost 97-99%. only Crysis and Crysis Warhead struggled to utilize more than 70%, it seems those games are specially optimized for Intel CPU. And Prototype 2 seems badly programmed too, sometimes it even struggles to utilize my 5770. And I don't think I need to describe about GTA IV (more cpu frequency more frame rates).

Well...at least games are running fine smile.gif It seems that those calculations we've done might probably be a bottleneck for GPGPU computing.
It feels a little odd that AMD with his HSA is trying to improve APU computing to max while their current generation CPU/chipsets are way behind to utilize current generation GPUs in term of GPGPU.

^ well this doesn't matter for most gamers as far as games are running smooth smile.gif

Hopefully they will focus all of their strengths on steamroller and make it deliver.

AMD's plan is to transition all their CPUs into HSA APUs, from their server to desktop mainstream to enthusiast lines. The current FX CPUs are really just a stop-gap measure until fully HSA-enabled enthusiast APUs are available.

Why is it, that anytime AMD has a product in the market that is performance competitive in its price class, gloom and doom news starts fudding out of everywhere you can imagine, even Rory Reed confirmed that they were making no changes to the 2013/2014 product maps, why would they ? most of this stuff is already in the testing phase or taped out and getting tested etc as engineering samples.

Would intel please stop spreading fud about its competitors already, this is getting old.

Yes you are right !
I believe too their CPUs are fine, they just need to implement PCIe 3.0 with improved memory controller as well. As till now I don't see any sign of this. But I also have a feeling they will get successful if they don't quit.

From what I've read, they've isolated the main cause of the slow L3 cache. However, addressing it is not a priority with Steamroller, it will be addressed with Excavator.

PCI-E 3.0 will probably appear on FM2 first, or the successor to the AM3+ socket. I highly doubt we will see PCI-E 3.0 on AM3+. Considering there is virtually no performance benefit with PCI-E 3.0 for typical AMD systems (you will not be using a FX-8350 with tri-SLI 680s or tri-crossfire 7970s), there's no reason for AMD to invest resources into a dated socket that's badly in need of a complete replacement. Unless, of course, they decide to not do an integrated NB for their enthusiast CPUs.
