Haswell vs Kaveri

The picture says GT2 has 20 EU and 2 "S", GT1.5 has 12 EU and 2 S, GT1 has 10 EU and 1 S (GT3 has 40 EU and 4 S)
What is an "S"?
 
Where was GT1.5 mentioned before? I must have missed it. Also, in the official developer's guide, HD4200 is said to have 20 EUs. And if the desktop HD4200 has GT1.5 while the mobile HD4200 has GT2, it gets even more confusing.

Namings are a lot arbitrary, and TDP constraints you a lot, possibily more so than what amount of units you've got there.
HD5000 even is slower than HD4600 it seems, but that HD5000 is on a very low wattage part (15 watts!, one of Kabini's power targets).

They do that dance already with a mobile/SFF i5 being the same chip (dual core + HT) as a desktop i3, and slower. So an i5 is slower than an i3.
It's possible too that a desktop GT1.5, clocked higher than a mobile GT2, gets the very same performance anyway or slightly better.

By the way, the thread could be titled "Haswell vs Kabini" when dealing with the low wattage part. They seemingly compete for Surface Pro and friend tablets, or some laptops. Low watt Richland and future Kaveri muddy things. Maybe next-gen Atom will be a huge success and I wonder if it has the very same graphics as Haswell.

Goto reported 4 months ago: http://pc.watch.impress.co.jp/docs/news/event/20130306_590559.html

Or vr-zone in April: http://chinese.vr-zone.com/61232/ha...-nvidia-gt640-and-amd-radeon-hd6670-04282013/

It's also in the driver since a couple of months. GT1.5 is for desktop only (HD4400). i3-4310 dualcore is using a GT1.5.


edit: looks like GT1.5 is an option for ULX as well.

Bay-Trail atoms have Ivy Bridge Gen (== gen7) graphics which is not all that different but only 4 EUs so more like "GT0.5". It is not exactly the same as Ivy Bridge graphics though it supports for instance (not even Haswell supports that) etc1/etc2 texture compression (seems to be just about the only difference though to GT1 gen7 graphics).
I'm not quite sure what I should think about GT1.5, is that some different die? It's noteworthy that it doesn't exist (at least so far) in the linux driver, maybe that's a GT2 with disabled units or something?
 
I don't expect Kaveri available before mid 2014 to be honest, also it is known since January this year that Kaveri is a 2014 product.
 
Well it is a good thing I didn't try to wait for the 28nm products.
:LOL: I was actually thinking about the successor of Kaveri as possible candidate for my next PC or laptop... I might get to old to care when the thing actually launches... :LOL::LOL:

I think they might be focusing on getting Kabini out in the market given the fact that it fits the price/performance bracket they need for tablets and other cheap mass market devices.

Kabini is already shipping. You can buy some laptops and PCs with Kabini from Newegg, for example.
 
You are probably thinking of Berlin, Kaveri's server market derivative.
Kaveri for laptops and desktops is still due in 2H2013 according to AMD's latest roadmap:

That's a showcase Roadmap. In January AMD itself told that they are planning to ship desktop Kaveri very late in 2013, means Kaveri this year was never the plan and a realistic target. Don't be fooled by AMDs public showcase Roadmaps.

We have also talked about our Kaveri APU in the second half of the year. We are on track for that.

Whatever anyone has read before then is overwritten by this statement during the Q1 conference call. We will get their Q2 conference call tonight.

There are a few possibilities here, assuming the delay is correct. It could be because of the sluggish sales of desktop meaning the OEM's are still sitting on Richlands (most likely reason imo), it could be that consoles are getting top priority (good chance of that one) or it could just be that it's another Bulldozer. Obviously it could be a combination of reasons that made them decide to hold off.

Remember that AMD gives shipping dates for their APU's, not dates for actual products with them (as they have little control over that).

I have a terrible feeling that this is the culprit, also bulldozer and piledriver chips are easy to find.

Filling retail with mediocre chips and then by the time they make a decent chip no one will stock it because they have too much of the previous models.
 
As Jimbo said, there's another conference call tonight, and AMD will almost certainly address the issue.
