The AMD Kabini Review: A4-5000 APU Tested
by Jarred Walton on May 23, 2013 12:00 AM ESTKabini: Competing in the Evolving Marketplace
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.

I'll beg to disagree with that. As a non-promotional price, for a notebook with a 1080p touchscreen display I think that 500$ is more than fair. As for promotions happening your line of reasoning seems to assume that discounts will only affect Intel notebooks which isn't clearly the case.While you may get cheap Ivy Bridge notebooks when in promotion, go search for cheap Trinity/brazos notebooks with promotions and you'll find them even cheaper. The same will be said of Temash/Kabini notebooks.
I fail to understand why you don't seem to acknowledge that.
Or the proposition of an APU that beats Pentiums and Celerons in performance (excluding single-thread performance, which is much less relevant nowadays) and has superior battery life.
Will Atom and Haswell Pentiums offer better performance/efficiency/price ratio? It remains to be seen.

Depends really. With a 1080p screen its a good price. Sales happen all the time. Yes you can and will get i3 ULV systems for cheap and can get kabini systems for cheap. I'm simply saying given the fact that these promotion happen all the time literally (go to newegg laptops, sort by price-lowest and more than 75% of the notebooks on that page are on sale) you have to take these things into consideration. Kabini is competing against discounted but perfectly fine notebooks in this segment. You can get a nice lenovo g580 with SV i3 for $350. Any promotion that runs with a kabini notebook will have to match that price/perf and kabini is much weaker than SV i3.http://www.newegg.com/Product/Product.aspx?Item=N8...

Sale % was taken from .ca g580 price from .com for .ca about half are on sale.dusk007 - Thursday, May 23, 2013 - link
The performance quite poor and notebookcheck doesn't really tell a different story. An i5 is the right CPU to compare it too because it runs in the same performance envelope. With all the other stuff that goes into a decent notebook or tablet/hybrid the CPU cost alone does make that much of a difference.The problem with Kabini is Single Threaded performance which matters for responsivness in plain old office work loads. Which is what most of these notebooks do. x264, cinebench, ... none of that really matters.
And gaming. In game low settings don't do much for CPU requirements and that is why even at low many games aren't playable. Something Intel can offer despite its HD 4000 which has nowhere near the reputation of AMD's GCN. If all you want is an office notebook for some casual gaming like a bit of Starcraft. An i5 is still a worthwhile investment.

The i5 is the right CPU because it runs in the same performance envelope??????? How about no??How much more does the i5 cost?
andrewaggb - Thursday, May 23, 2013 - link
Well theres two arguements. One is cost, and yes amd will come in cheaper because intel likes their margins. So if cost is your primary motivator than this chip looks good.The other argument is performance/watt and peak performance, both of which make an i5 look much better than this chip.
Now it's true an i5 doesn't scale down to 3.9W, so in that market this chip appears to be a real contender and the one to beat. But that's not the version that was tested here today so we don't know that for sure.
Personally, I'm disappointed, and think haswell will compare very favorably in all metrics except price. I'm not sure haswell will be tablet suitable though, where some sku's of this chip should be.
Not saying this chip is terrible, just saying for anything 8-9W and up it seems to me haswell will be the clear choice if price isn't a major factor.

And this is a product that competes on price and battery life. Not performance as Haswell does.dusk007 - Saturday, May 25, 2013 - link
Just that it does compete on performance doesn't mean performance isn't valuable information. How much speed loss are you dealing with when going with cost effectiveness. This isn't a smartphone CPU that will ultimately end up running different software. It is still Windows and the same games and programs as an i5 is used for.The cost difference in the end product isn't that huge or insurmountable. The buyer would like to know how much they get when paying up or who much they loose when going cheap. Comparing it only with Atoms would be cheating and something marketing folks do not a review site that wants to have some reputation.
These chips don't go into Smartphones not even Tablets (that is Temash) they go where 15W Haswells will go and 2/3 of those sub $800 notebooks BOM is still none CPU related. So even if Kabini was given away for free the notebooks would still cost something.

But price is always a major factor. It's the "majorest" factor. This is a site for enthusiasts (read geeks) but think of the person at the AT&T store who picks the 2 or 3 generation old iPhone because it's $50 cheaper.tunaman - Thursday, May 23, 2013 - link
AMD set the standard with x64 that Intel evetually agreed was superior and joined. With the introduction of these hUMA (fully shared CPU and GPU memory) chips AMD has again set the standard that Intel will have to copy.As I've said before; Intel hasn't been a tech leader in a decade and, again, they'll be playing catch up once they cave to AMD's superior design. But by then, just as has been true for years, Intel graphics and multitasking will continue to lag behind AMD. Intel's only bragging right is saving one or two watts and slapping an "Intel Inside" tatoo on products, but charging twice as much for it. http://goo.gl/OItwV
