[tomshardware] AMD's Kabini: Jaguar And GCN Come Together In A 15 W APU

post #1 of 24

Before we try to reach any conclusions, check out the following chart summarizing performance in each of our benchmarks. Pay particular attention to those orange bars, which represent power efficiency. This is the relationship between each platform's power draw and average performance.



On one hand, the Kabini-based A4-5000 doesn't fare very well when it comes to charting frame rates in games and the time it takes to complete our wide range of desktop workloads. It gets beaten by the dual-core Pentium B960 in every discipline except gaming. But the efficiency bar tells a very different story. Even if you can get Pentium B960-based notebooks fairly inexpensively, you certainly cannot expect them to deliver great battery life with that 35 W processor in there.

Mod edit: Please use the same title as the article and only quote the first paragraph, not the whole article.

I don't really get their testing methodology. The intent with these chips is similar to the intel atom: to be put in devices with long battery life, 10 hours or more. None of those machines will be gaming powerhouses, in fact the Atom is just as much of a joke in gaming benchmarks.

I really have no idea what Toms is doing with their testing here, TBH - it's like they're testing the Kabini by the same metric a full blown, full size laptop would be tested. It isn't for that market - these chips are designed as low power, long battery life devices for tablets. Not gaming powerhouses. Just IMO.

Their methodology makes absolutely no sense at all to me.

"Hey, this processor is up to par with the Pentium B960, beats it in gaming and power efficiency even though it's targeted against Atom processors BUT since you can get a cheap $360 Core i3 laptop at the same price, why not get the Core i3?"

Yeah, I don't really go there much anymore. Especially after they blocked my account from ever commenting on their stuff and deleted any questions I had about what was going on.

What did you even do??

On topic: The Kabini's power draw is almost half of the i3 3217U and it has alright performance, thus its worth it.

What I hate more than crappy iGPUs is a low battery life. Right now my Samsung single core Atom lasts 6 hours surfing, while my Toshiba Athlon X2 only last 30 minutes max sufing.

I used swear words in one of my posts months ago, when I had a really bad day, not directed at anyone though. That was grounds for a week of suspension without warning, and apparently permanent block from posting except in the forums. I believe trolls received lighter treatment.


Anyways, two years ago, my dad bought a Samsung i3, 3lb 11" laptop that only had 2 hours of surfing, not max load. I think the "i3" and the cheap price tag was sufficient to get him to buy the laptop.

Sometimes I want to just job shadow a laptop designer/engineer or a manager at an OEM, and see what their thought processes are...

Thread title seems a bit misleading as the performance isn't medicore for an atom sytle chip at all.

Should read, Kabini powerful, power efficient chip lol.

Bizarre test methods from Tom's as well. Guess they need to make AMD look bad somehow...

I wonder which is worse: Tom's Hardware's A4 review, or Anandtech's A4 review?

Temash looks more like the mobile SOC for tablets and direct competitor with Atom. Kabini is on a higher power envelope (A4-5000 have a 15W TDP which requires active cooling, Atoms are in sub-4W TDP SOCs and don't need active cooling), and seems more like a low end notebook solution that competes with Celeron/Pentium.

Kabinis are not in the same power envelope as Atom.

hope Haswell and bay trail really do change what we've come to expect from the mobile platform. Great progress by AMD, there just needs to be a better way to measure performance. Saying you're better than an outdated atom isn't really telling of much.
