AMD - Piledriver chitchat

[Biscuit]

It seems the A10 5800K was demoed recently:

It still looks like desktop parts are a few months away.

It also seems Trinity based Opterons are inbound too:

Interesting how that story fills in the puzzle regarding apple and their retina displays. Would have made a pretty good combination with AMD chips and would have had a massive boost for AMD both in sales and their public profile.

AMD talks about a Trinity based Opteron:

i really hope piledriver delivers - we need more diversification

You and me both, been looking at an upgrade to my machine for a while now.

I love AMD and have been using them since the Athlon 1800+, currently have a 965BE and was hoping BD was going to be EPIC but I was put off, now going to wait till Sept (heard a rumor that PD was going to be in sample at least by then so should have some prelim reviews) but I may have to look at the blue side.

I'd be glad of a platform upgrade, the current one is falling behind in terms of idle power consumption and efficiency, but they have enough to worry about right now I guess. Just my rig in spec idles at close to 100w, albeit with 5870, HDDs, fans, 4 DIMMs, but my Llano system manages 25w or lower idle, a good chunk of that probably being the power supply, which tend to idle between 5 and 10w. Yet, try to find a decent PSU below 350w and with half decent efficiency at what are now realistic idle loads. But I digress, it will be interesting to see how PD performs, and I'll be personally looking closely at power efficiency.

Me and a friend of mine were going to get bulldozer but many were saying how it wasn't what it should have been, hopefully piledriver is much better and is worth the wait

The Piledriver cores in Trinity already seem to have upto 15% improvement over the Bulldozer cores in Zambezi:

I would read the review of the A10-5800K. Vishera will have L3 cache like Zambezi and unlike Trinity which lacks it. So it could mean around 20% to 25% improved IPC over Zambezi.

Upto is the most important word in that. I would have thought for most things it will under 10%

That Tom's review came out of nowhere, is that the only one their is ATM?

I am being conservative TBH.





In both instances,the same number of threads were used. However,in both cases the cores in the FX8150 had access to more L3 cache per core than normal.

The first test is single threaded and the second uses 4 threads. This means the A10-5800K is probably faster than an FX4170 in many instances.

So this looks faster than a Core i3 2100 in this application.

In many applications it seems to be around the same level as a 3.2GHZ to 3.4GHZ Phenom II X4,and many do much better on a Phenom II X4 than a Llano A8 due to L3 cache.

In some applications,performance is better than any current AMD CPU.

I suspect that with L3 cache,Vishera might have very close to Deneb IPC but hitting much higher clockspeeds.

In multi-threaded applications the FX8350 is probably going to very competitive with a Core i7 3770K IMHO. In applications such as gaming,I suspect lightly threaded thread performance is going to surpass Deneb by a reasonable amount.

Yep.

It seems in some situations,the A10-5800K is faster than any Phenom II or FX CPU.

The FX8350 will not only have twice the threads of the A10,but has L3 cache and AFAIK will also have additional modifications to the Piledriver cores.

If you add in the fact it probably will have a clockspeed boost,I suspect it should be at least 25% to 30% faster in many workloads. Hence,in multi-threaded workloads should be as good or better than the current IB Core i7 CPUs IMHO. Single threaded performance might be not as good,so I expect a Phenom II X6 against Core i5 700 series level matchup.

Not sure how much gaming performance will increase,but it probably looks like it will better than the Phenom II consistently.

[watercooled]

Phenom II X6 against Core i5 700 sounds like a good comparison IMO. I suspect they're going for a similar TDP with both the APUs and CPUs now, with the GPU part replacing half of the cores in the APUs.

It looks Insight has a Samsung A10 based laptop for under £600:

that looks lovely

Typical crappy useless screen res though...

Indeed. How much longer are Laptop manufacturers going to keep short-changing us with these appalling resolutions. You know, in a lot of ways I really wish they'd drop to 1280x720 instead - at least that's a proper 16:9 resolution! Although 1440x810 would be better (and 1440x900 perfect on a 15", IMNSHO). Even tablets are getting 1280x800 screens now. 1366x768 is just such a cop out...

[DanceswithUnix]

1366x768 works nicely on my 11.6" Brazos box. Don't get why they use it on bigger laptops, let alone 32" TVs.
