AMD Propus to be released in Q2 & Q3

Friday 13th February 2009, 10:10:00 PM, written by Arun

Back in 2008, we talked a few times about AMD's Propus chip - basically a Deneb with no L3 cache and 5-10% lower performance in desktop applications - and how important it is to AMD's prospects in the desktop market. Now Fudzilla claims a 45W EE SKU is slated for early Q2 and others for early Q3.

This is certainly later than we had hoped (heck, initially we were so optimistic we thought it would be released sometime in Q4 - oops!) but at least it catches the Back-to-School OEM cycle perfectly, assuming this leak is correct (we think it is, and Fudo was the first to talk about Propus). This chip should be much more competitive than Barcelona or even Deneb from a perf/dollar point of view. It's unlikely to be low enough power for the notebook market however (and it turns out L3 might actually save power there, since it minimizes external memory accesses), and doesn't seem to make any sense for servers.

We'll see what happens, but given Intel's delays for some Nehalem chips recently and a couple of other factors, AMD's position in 2H09 could be an awful lot worse. Whether they can maintain that position in 2010 following Intel's 32nm ramp appears highly unlikely, but it's hard to say just how bad it's going to get.

Are there any laptops planned with these CPUs ?

Relative latency of the main memory system more than halve when the CPU is throttled down to 0.8-1 GHz for battery operation, reducing the impact of lacking a L3.

Cheers

That'll come in 2010. The September refresh of Athlon/Turion IIs will only include Regor AFAIK.That's rather nifty, but I do wonder if the extra power consumption is worth it in this case. The current Turion X2 Ultras (Griffin) already do it with a separate NB component & power plane I think.

That's true, but I'd say this is definitely necessary, those Turion X2 Ultras can hardly compete with mobile intel celerons. Those mobile regors should be faster (both because of the core improvements and possibly slightly higher frequency) and I'd expect them to not draw more power (Griffin is still 65nm). Nothing to threaten the better mobile core 2 duo cpus, but at least something competitive at the lower end.

A small update.Looks like AMD is going for an all-out price war vs the Q8 series. They can afford to, in a sense.Image: http://news.mydrivers.com/img/20090711/S02202920.jpg

The quad core Caspian should come with some transistor improvement. So should Magny-cour I guess. They both need it. Image: http://www.impresswatch.com.cn/imagelist/09/25/ynw6ui3655p7.jpg

I don't follow you there. Caspian is the dual-core followup from Griffin (rumours said actually it might be shrinked Griffin but looks like mobile Regor to me). Champlain is the future quad-core mobile part (looks like mobile propos...). Magny-Cours it the monster 12-core chip (actually it's mcm with 2 sao paulo).
I'm not sure what improvements actually there are expected? Faster switching speed (hence higher possible clock), more densely packed transistors or what? There doesn't really seem to be anything on the published AMD roadmaps indicating that.

Oops I mixed up the code name and yes I meant to say Champlain. It's just that with today's 45nm AMD cpus they won't be able to make Champlain/Magny-Cours with acceptable clock speeds. So the process has to improve to make those. The slide indicate new strain techniques which If I am not mistaken can help cpus achieve clock speeds with lower voltages(You can have faster clock or same clock with lower voltage), hopefully enought to maintain a, say 2.5GHz and slip Champlain into a 35w thermal. Or I could be they are working on something like Intel's Turbo Mode to cheat the thermal wall. I could be they will have both but I might be too optimistic.

Champlain's target clocks wrt Propos-energy efficient is actually okay.2.2, 2.3Ghz - 45W, + NB.Calpella Nehalems (Clarksfield), according to HKEPChttp://global.hkepc.com/34771.6Ghz 6MB - 45W - $3641.7Ghz 8MB - 45W - $5462.0Ghz 8MB - 55W (XE) - $1054If Clarksfield is 45W, then AMD should have some good chances with lower (< 300USD) pricing. It's K10 and it's 2.2Ghz... it just doesn't have Turbo mode (which should be appreciated much more on the laptop segment, I guess) ;)

those are very high prices (as much as a full computer), Intel wants high margin high end laptops, perhaps with an Intel SSD along it.I believe propus will actually compete with dual core nehalem and then dual core westmere. They will best each other depending on the tasks you run.

There will be no dual core nehalem. Havendale/Auburndale are canceled, with the westmere parts (clarkdale/arrendale) appearing a bit earlier than originally thought.

Something like a 3Ghz dual-core westmere part will obviously run circles around a 2.2Ghz propus for single/dual-threaded workloads (unless amd implements turbo-like abilities, even then it can't win). Even with heavily multithreaded apps it could be quite close. And I fear in terms of perf/watt it will not compete neither (of course, you could say that's unfair a 45nm part against a 32nm part...). Maybe those improvements GF mentioned indeed help, but I dunno I wouldn't expect drastic improvements from it.
