Sandy Bridge Integrated Graphics Performance

With Clarkdale/Arrandale, Intel improved integrated graphics by a large enough margin that I can honestly say we were impressed with what Intel had done. That being said, the performance of Intel's HD Graphics was honestly not enough. For years integrated graphics have been fast enough to run games like the Sims but not quick enough to play anything more taxing, at least not at reasonable quality settings. The 'dales made Intel competitive in the integrated graphics market, but they didn't change what we thought of integrated graphics.

Sandy Bridge could be different.

Architecturally, Sandy Bridge is a significant revision from what's internally referred to as Intel Gen graphics. While the past two generations of Intel integrated graphics have been a part of the Gen 5 series, Sandy brings the first Gen 6 graphics die to market. With a tremendous increase in IPC and a large L3 cache to partake in, Sandy Bridge's graphics is another significant move forward.

Is it enough to kill all discrete graphics? No. But it's good enough to really threaten the entry level discrete market. Take a look:

Batman: Arkham Asylum

It's unclear whether or not graphics turbo was working on the part I was testing. If it was, this is the best it'll be for the 6 EU parts. If it wasn't, things will be even faster. Comparisons to current integrated graphics solutions are almost worthless. Sandy Bridge's graphics perform like a low end discrete part, not an integrated GPU. In this case, we're about 10% faster than a Radeon HD 5450.

Assuming Sandy Bridge retains the same HTPC features that Clarkdale has, I'm not sure there's a reason for these low end discrete GPUs anymore. At least not unless they get significantly faster.

Note that despite the early nature of the drivers, I didn't notice any rendering artifacts or image quality issues while testing Sandy Bridge's integrated graphics.

Dragon Age Origins

The Sandy Bridge advantage actually grows under Dragon Age. At these frame rates you can either enjoy smoother gameplay or actually up the resolution/quality settings to bring it back down to ~30 fps.

Dawn of War II

It's not always a clear victory for Sandy Bridge. In our Dawn of War II test the 5450 pulls ahead, although by only a small margin.

Call of Duty Modern Warfare 2

Sandy is one again on top of the 5450 in Modern Warfare 2. Although I'm not sure these frame rates are high enough to really up quality settings any more, they are at least smooth - which is more than I can say for the first gen HD Graphics.

BioShock 2

Intel promised to deliver a 2x improvement in integrated graphics performance with Sandy Bridge. We're getting a bit more than that here in BioShock 2.

World of Warcraft

World of Warcraft is finally playable with Intel's Sandy Bridge graphics. The Radeon HD 5450 is 10% faster here.

HAWX

Sandy Bridge Graphics Performance Summary

This is still a very early look. Drivers and hardware both aren't final, but the initial results are very promising. Sandy Bridge puts all current integrated graphics solutions to shame, and even looks to nip at the heels of low end discrete GPUs. For HTPC users, Clarkdale did a good enough job - but for light gaming there wasn't enough horsepower under the hood. With Sandy Bridge you can actually play modern titles, albeit at low quality settings.

If this is the low end of what to expect, I'm not sure we'll need more than integrated graphics for non-gaming specific notebooks. Update: It looks like all notebook Sandy Bridge parts, at least initially, will use the 12 EU IGPs. Our SB sample may also have been a 12 EU part, we're still awaiting confirmation.

    Just something like nVidia Optimus? Perhaps Intel could come up with a more elegant solution to the same problem...

    Hmm, based on the roadmap I actually think the i7-2600K will be priced close to the i7-875K. The i7-950 is supposed to drop to $294 next week putting it in the high end Mainstream price range (it'll still be Q3'10 then). Also, all the $500+ processors are in the Performance category (i7-970, $885; i7-960, $562; i7-880, $562).

    If the i7-2600K goes for $340 or thereabouts, I can already see supply shortages due to high demand (and the eventual price gouging that would follow).

    How are the comparisons between NVIDIA low end discrete/mobile graphics?
  • tatertot - Friday, August 27, 2010 - link

    Hey Anand,

    How could you tell that this sample had only 6 execution units active in the GPU vs. the full 12?

    Was it just what this particular SKU is supposed to have, or some CPU-Z type info, or... ?

    thx

    Right now all desktop parts have 6 EUs, all mobile parts have 12 EUs. There are no exceptions on the mobile side, there may be exceptions on the desktop side but from the information I have (and the performance I saw) this wasn't one of those exceptions.

    Take care,
    Anand

    "all mobile parts have 12 EUs"

    Sweet! Guess the good 'ol GeForce 310m is on the way out.
  • mianmian - Saturday, August 28, 2010 - link

    The mobile CPU/GPU usually has much lower frequency.
    I guess the 12EU mobile GPU will perform on pair with the desktop 6EU one.
  • IntelUser2000 - Saturday, August 28, 2010 - link

    That seriously doesn't make sense. Couple of possible scenarios then.

    -Performance isn't EU bound and 2x EUs only bring 10-20%
    -The mobile parts are FAR faster than desktop parts(unlikely)
    -The mobile parts do have 12 EUs, but are clocked low enough to perform like the 6 EU desktop(but why?)
    -There will be specialized versions like the i5 661
  • DanNeely - Sunday, August 29, 2010 - link

    Actually I think it does. Regardless of if they 6 or 12EU's it's still not going be a replacement for any but the bottom tier of GPUs. However adding a budget GPU to a desktop system has a fairly minimal opportunity cost since you're just sticking a card into a slot.

    Adding a replacement GPU in a laptop has a much higher opportunity cost. You're paying in board-space and internal volume even if power gating, etc minimizes the extra power draw doubling the size of the on die GPU will cost less than adding an external GPU that's twice as fast. You also can't upgrade a laptop GPU later on if you decide you need more power.
  • Anand Lal Shimpi - Tuesday, August 31, 2010 - link

    I spoke too soon, it looks like this may have been a 12 EU part. I've updated the article and will post an update as soon as I'm able to confirm it :)

    Take care,
    Anand
