The Sandy Bridge Pentium Review: G850, G840, G620 & G620T Tested

The Sandy Bridge Pentium lineup features the performance equivalent of Intel's HD Graphics 2000. AMD's A6-3650 on the other hand sports a 320 core GPU called the Radeon HD 6530D. How do the two stack up? What about compared to the A8-3850's Radeon HD 6550D? We're about to find out.
We'll start with the A6-3650 vs. the Pentium G850. I didn't include the slower Pentiums because there's simply no point to. The A6-3650's Radeon HD 6530D GPU is on average 2.33x the speed of the Pentium G850 across all of our tests and all resolutions. There's simply no competition and at these frame rates, even at 1024 x 768, I wouldn't consider the G850's graphics playable unless you go to older games or really make the game look terrible.
AMD A6 vs. AMD A8
What about the AMD A6 vs. A8? On average the A8's higher GPU clock and 80 extra GPU cores give it an 18 - 26% performance advantage over the A6's GPU depending on resolution. Both systems here use DDR3-1600 memory and despite memory bandwidth being constrained across the board, the A8's advantage increases with resolution.

The sad thing is AMD is still using a CPU core then is two generation behind Intel. We will have to wait for Bulldozer + updated GPU for a decent low end CPU.However by the time Intel would have either Ivy or Haswell ready.
AMD you need to work harder.

iwod, you may have waited, and achieved: massive, epic failure, amd style...Since amd still has to be sold with endless lies, everyone knows the answer that few are willing to admit.
I congratule on amd lying about bulldozer transistor count, fanning their fanboys to the outer limits of worshipful surrender.

Now that Firefox and IE9 support GPU acceleration, adding these to the CPU benchmarks SHOULD be seen as fairly important when talking about low to mid range processors/GPUs. I suspect that if running Firefox 6 with Flash(due to banner advertisements and such), you might see some interesting results on a per-core basis between the AMD A6 and Intel Pentium chips reviewed here.fuzzymath10 - Tuesday, August 23, 2011 - link
I'm pretty sure you need only DX10 for that. My laptop's x3100 IGP from 2008 supports h/w rendering because the driver is DX10. Flash video decoding is more restricted, but it's possible the new Intel IGPs will work since they have DXVA decoding of h.264.Targon - Tuesday, August 23, 2011 - link
The GPU acceleration obviously will be better with a faster GPU in browsers and Flash, and that helps level the playing field in this case. I would like to see how much it levels the playing field.JarredWalton - Tuesday, August 23, 2011 - link
If you have a good benchmark for measuring performance in IE9 and FF6, I'd love to hear it. Sure, I can open up a Flash video, but on any modern GPU (including Arrandale's IGP), it's not a problem. Even GMA 4500MHD could handle Flash video content with the latest drivers (helped by the CPU of course).The problem is coming up with a meaningful benchmark with browsers. Are we supposed to look at CPU usage while watching a video, or power usage? Do we go to some weird web page benchmark that stresses the GPU accelerated portions of the browser, even though 99% of web sites look like our site and don't benefit? I've got from Firefox 1 through 6, most versions of Chrome, every major Internet Explorer release, and I've even dabbled with Safari (sucks on Windows!) and Opera. Unless you're playing Flash games, I haven't ever felt that any of the browsers was "too slow"; mostly I stuck with FF for the extensions, but I've moved to Chrome now. Both still run fine whether I'm on IGP or dGPU.
I guess my point is, sure, you can create a browser test that stresses GPUs/CPUs to the point where it's a benchmark, but is it actually useful data? If a web site is putting a 100% load on your CPU, GPU, or both, it's a poorly designed site for normal use.

I have bought few months ago 620T, compared to AMD I was previously using, power consumption is much smaller, same goes for noise, I can't hear it with stock cooling.My whole computer with high quality PSU, 3 HHDs (all power saving), a DVD and some basic ASUS motherboard takes only 60W in stress, and for things I do with this computer, it's far more superior than AMD.
I should mention, that I use my computer as server for backups of my customers servers, so I need high IO rate without any bottlenecks, and AMD always gave me problems with that. For example, AMD had problems while I wanted to watch a movie, while 2 servers were sendbing backups to my computer and saving it to LVM on software RAID array.

On page 3, the link to "Bench" is broken in the second sentenceAlso, the hardware setup lists a Corsair drive for the Hard Disk, but then 2 paragraphs down references the Intel XM25-M ?

The Bench link looks fine here. What are you seeing?koan00 - Tuesday, August 23, 2011 - link
It initially linked to "http://www.anandtech.com/show/4524/the-sandy-bridg... but it appears to be correct now. Thanks.
