The AMD Kabini Review: A4-5000 APU Tested

Prior to the onslaught of Android tablets and the launch of Windows 8, I was pretty much done with Atom and Brazos—they simply didn’t provide enough performance to make them pleasant devices for me to use. What was rather anemic hardware for Windows Vista/7 starts to look much more palatable with the new OS, and Android on such a chip can run extremely well. AMD has Temash for that audience, but I suspect we’ll at least see some 15W Kabini tablets/hybrids at some point, and they should stack up quite well against the competition in terms of performance and features. That’s the real takeaway from today’s launch, and it shows that AMD is keen to carve out a market niche separate from the traditional desktop and laptop PCs.
In terms of the normal Windows experience, Kabini doesn’t make too many waves. Yes, it’s faster than any current Atom or Brazos laptop, and Windows runs reasonably well all things considered, but there are still applications where Kabini falls short. That's the problem with competing in the good enough part of the computing spectrum—everyone has a different definition of what's good enough.
CPU performance is appreciably better than anything Bobcat or Atom based at this point. If you're ok with Clover Trail, then Kabini will feel really quick. The big Ivy Bridge cores still maintain a significant performance advantage, but presumably Kabini's offer is that you can find it in an Ultrabook-like system but at a much more reasonable pricetag. If that ends up being the case, I suspect many would choose form factor over extra CPU performance. So much of Kabini's success will be tied to what OEMs do with the parts. It's unfortunate that AMD doesn't have any Kabini APUs with Turbo Core working as I suspect that could do wonders for further driving single threaded performance.
On the graphics front, Kabini's Radeon HD 8330 is stuck between a rock and a hard place. It's significantly faster than what we had with Brazos (and lightyears ahead of what you get with Clover Trail), but not faster than Intel's HD 4000 which we viewed as the minimum acceptable level of performance for processor graphics upon its introduction. However, if you're playing older titles, or when faced with more tablet-like 3D workloads, Kabini's GPU should do very well.
On the power front, Kabini is great. In our tests we found much better battery life than Brazos and even better battery life than 17W Ultrabook-class Ivy Bridge parts. The days of AMD being associated with poor battery life are long gone. Kabini manages compelling battery life and better performance than Brazos, which is exactly what AMD needs. Given how successful Brazos was (almost 50M units shipped), Kabini seems to have the right recipe.
The real question for me is what sort of laptops and devices we’ll see when manufacturers release Kabini into the wild. The prototype laptop is really weak on some areas I care about—the keyboard and touchpad just don’t impress, and build quality is flimsy at best—but what it does have is a great LCD for what will hopefully be a budget-friendly laptop. Give me a reasonable Ultrabook-style chassis (or maybe a dockable tablet) with Kabini and a decent quality 1080p touchscreen and do it at the right price and there are plenty of people that will jump at the offer.

Because no one cares about Sandy Bridge ULV considering its now end of life. They also tested a lot of highly synthetic benchmarks. i3 ULV ivy notebooks can be had for $400 on newegg, i5 ULV notebooks cost $500 (http://www.newegg.com/Product/Product.aspx?Item=N8... sale yes but sales happen all the time). Also for the greater part of its lifetime, kabini will compete with haswell.Gaugamela - Thursday, May 23, 2013 - link
No, Kabini will compete with Pentiums. You guys keep forgeting that.And Ivy notebooks will be replaced and Kabini notebooks won't compete with them for most of it's shelf life. As for sales, do you think you won't see sales of Kabini notebooks?
Just because there's a small overlap of vendors clearing up inventory of Ivy notebooks doesn't invalidate that Kabini is a new chip and won't compete with Ivy Bridge for most of its life.

No, if an i5 ULV notebook costs $500, an i3 ULV notebook costs $400 and a kabini notebook costs $450 then the kabini is competing with i3/i5 and NOT pentium. Pricewise it competes with i3 and possibly i5. Haswell ULV will launch in a few months. Bobcat launched what? two years ago. With a similar lifetime (hope its shorter) jaguar will be competing with haswell for the vast majority of its lifetime.t.s - Thursday, May 23, 2013 - link
Yep. The barrier IMO, is OEM. OEM tend to hiking the price. When bobcat E350 first out, the average price is ~$360. What the hell. With $460, i can get 2x performance with sandy bridge i3.If only AMD want to build their own machine (laptop and desktop).

A Kabini notebook costs 400$. And that's without having into account promotions, which WILL happen just as they happen to those precious i3 Ivy Bridges of yours. You seem to forget that promotions happen to all notebooks. And if you keep bringing ULV i3 Ivy Bridges for that price, then guess what? I'll get a TRINITY APU notebook instead for that price! Because I can also get them!! And they have a much stronger GPU power than Kabini, and Ivy Bridge and I can also get some quite decent ultrathins.whyso - Thursday, May 23, 2013 - link
Trinity and ivy bridge ULV are very similar in gpu performance. ULV ivy demolishes ULV trinity cpu wise though.Gaugamela - Friday, May 24, 2013 - link
The top Trinity LV APU (the A10-4655M) beats the Ivy Bridge ULVs in terms of GPU performance. The issue is that there's barely any notebooks for sale with it (The Samsung Series 5 ultrathin is one, the HP Sleekbook another).The A8-4455M is available in the Asus U38N and a Lenovo model and that one is weak. It's comparable to a Ivy Bridge i3 em terms of CPU/GPU performance (weaker single-thread but better multi-thread - more cores).
However, Trinity powered notebooks are usually cheaper than Ivy Bridge ones and you can get them with great promotions now.

They are very similar and within error range (+/- around 10%).Gaugamela - Friday, May 24, 2013 - link
No, they're not. A A10-4655M with dual channel RAM beats the living crap of a HD4000. You just don't want to admit that. Go dig for benchmarks before spouting falsehoods.whyso - Friday, May 24, 2013 - link
No, mobile amd apus do very good in 3d mark but poorly in games because games have more cpu load (unlike 3dmark which is very cpu light) and the gpu can't boost as high. For instance the 7660G generally ties with the 630m in 3dmark but loses by about 20% in games. Thats a 25 watt part so it will do better than the 17 watt ULV but beat the living crap? NO. Even the 7660G only beats the HD4000 on average by 30%, move that down to ULV and the difference is less.
