Mobile IGP Comparison

I narrowed down the platforms for our mobile IGP comparison. I simulated a Core i3 350M by taking an i3-530, underclocking it (I couldn't do anything about the 4MB vs. 3MB L3 cache) and capping its GPU frequency at 667MHz. This is the best case scenario for the i3-350M, and as you'll see below, it doesn't really matter. I also paired a 2.2GHz Pentium Dual-Core with a G45 motherboard, agian simulating the cheaper mobile Pentium platform. Finally I installed Windows 7 on the 1.6GHz Core 2 Duo based 11-inch MacBook Air with its GeForce 320M to give you an idea of the upper bound for mobile performance with what might as well be a low end discrete GPU.

Updated: I've added performance results from a simulated Core i3-330UM, the E-350's competition in ultra portables.

We'll start with Modern Warfare 2:

Mobile IGP Comparison - Modern Warfare 2 - 1024 x 768 - Low Quality

The E-350 puts the i3-350M, i3-330UM and Pentium DC to shame, delivering 67% better performance. The frame rate is just shy of being totally smooth however. I found that in most modern games 1024 x 768 would result in frame rates just under 30 fps.

Mobile IGP Comparison - BioShock 2 - 1024 x 768 - Low Quality

BioShock 2 showed a similar performance advantage. Again we're not able to break 30 fps but the performance advantage is huge compared to the Intel platforms with integrated graphics.

Mobile IGP Comparison - Dragon Age: Origins - 1024 x 768 - Low Quality

Dragon Age: Origins is mostly CPU bound at low quality settings and thus there's no real advantage to the E-350's Radeon HD 6310 GPU. It's faster than the Pentium/G45 platform, but significantly slower than the i3-350M. I expect most games however to be GPU bound at these settings across the board.

Mobile IGP Comparison - World of Warcraft - 1366 x 768 - Fair Quality

World of Warcraft continued the trend. The E-350 ended up 57% faster than the i3-350M, although still fell short of a discrete GPU.

Of course I wondered how well Brazos would play Starcraft 2:

Mobile IGP Comparison - Starcraft 2 GPU Test - 1366 x 768 - Low Quality

The GPU handles SC2 just fine, however the game is very CPU dependent and thus you see a pretty big advantage from the mainstream i3 system. The comparison is a lot closer when we look at the i3-330UM. The E-350 won't be able to play SC2 as well as a $500 mainstream notebook, but it'll be comparable to an ultraportable running ULV Arrandale.

We don't have numbers for the G45 platform here because the system wouldn't run our benchmark (our tests use an older version of SC2 which apparently had issues with the G45 drivers).

Our SC2 CPU test gives you an idea of the lower end of performance in large multiplayer battles:

Mobile IGP Comparison - Starcraft 2 CPU Test - 1366 x 768 - Low Quality

The E-350 offers only 58% of the performance of the i3-350M system. The Bobcat cores do hold the platform back from time to time. Again, compared to the i3-330UM there's no performance difference at all.

Just for kicks I also ran the Civilization V benchmark, which gave us two datapoints: GPU performance and no-render/CPU performance.

Mobile IGP Comparison - Civilization V - DX10/DX11 - 1366 x 768 - Low Quality

The benchmark doesn't score well on either platform, although AMD does hold a 72% performance advantage over the i3 and G45 platforms. The CPU test puts the E-350 at about 55% of the speed of the Pentium dual core platform.

Mobile IGP Comparison - Civilization V - DX10/DX11 - 1366 x 768 - Low Quality

Civ V is one area where the Arrandale CPU advantage wins out over GPU performance.

Overall, the E-350 has no problems outperforming any of the current Intel integrated graphics offerings in 3D games. In CPU bound titles the E-350 loses out to the mainstream i3, but is competitive with ultra low voltage i3s. Just as with Atom, you'll have to sacrifice performance vs. a mainstream notebook, but compared to low voltage Arrandale the E-350 can hold its own.

    Yep, they should have definitely said something like "Here's a reasonably adequate product in its niche. Please buy it. Or not. There's lots of good stuff out there." ;)

    At any rate, Fusion is like Centrino - broad market speak for a concept, not any specific product. Trinity (the first Bulldozer+GPU) will be a 'Fusion' product just as much as Ontario, Zacate, and Llano are.

    "When it comes to power consumption however, the E-350 can't be touched. I measured max system power consumption at " ???

    Silly to compare E350 with Atom. You should have done C50/C30 comparison with Atom. Reply

    Unfortunately all we had access to was the E-350. As soon as there are C-x0 platforms available we'll review em :)

    Take care,

    Couldn't you have tried to cap the E-350 at 1GHz using Windows' power management settings? Or was Cool'n'Quiet disabled? Reply

    well, I guess it's still early to make a judgement in this product, and I should wait for the final version. But still, when I see it it's no different from atom on cpu power. when my expectation is this brazo at least 50% faster than atom, and this will upper the competition.

    Maybe I will more interest if the fusion is make a good boost on most of application.

    in this preview you 're putting E-350 against desktop processors (some of them really old), a dual core Atom and an ''i3-350M''.None of the above is in the same market AMD is targeting with this chip, which is the ultraportable market (11''-13'' screen).D510 has a lower TDP (13W) and i3-530M a much higher one (35W).As you stated, ''This is effectively AMD's answer to Intel's CULV platform, but with better graphics performance''.Please compare E-350 with the i7/i5-XXXUM line of processors,so we can really evaluate the performance of this APU.

  • Anand Lal Shimpi - Tuesday, November 16, 2010 - link

    Ask and you shall receive. I just updated the gaming benchmarks with results from a simulated Core i3 330-UM, will be adding the general performance benchmarks as well :)

    Take care,

    And while I am grateful for the update I was wondering if you could also test a
    1) Celeron Dual Core SU2300 or Pentium Dual Core SU4100 which are based off the Penryn CULV and go for about 450 to 700 online.
    2) Pentium U5400 aka the I3 Derivative with features turned off such as Multithreading since this is the closest priced Arrandale ULV you are going to find that competes with Zacate. Moste U5400 systems go for 580 to 700 online.

    Thank You

    AMD E-350 gets destroyed by core i3/i5 ULV cpus at the same wattage (18W for CPU/GPU).

    and sandy bridge will make this much worse for AMD in a matter of months.

    gpu performance is really not a concern for the type of products these processors are intended for. intel core i5 ULV IGP is good enough for video/flash-games etc.

    this seems like a total waste.
