Intel HD Graphics: A Lot Better

With Clarkdale Intel has finally dropped the Graphics Media Accelerator (GMA) prefix. Intel integrated graphics is now just called Intel HD Graphics.

The move to 45nm gave Intel the ability to beef up its graphics core a bit, but ultimately it’s the same architecture as the G45 - just faster. We won’t see Larrabee on a CPU for some years to come.

The GMA X4500 core from G45 had 10 shader processors. Intel HD Graphics bumps that up to 12. Apparently there are a number of internal tweaks and performance enhancements that should result in more than a 20% increase in performance though.

All integrated GPUs regardless of vendor, pretty much suck. Intel gets a bum rap because while other IGPs may offer 30+ fps in games at the lowest quality settings, Intel can often only manage single digit frame rates. It doesn’t take too much searching to prove that one.

Clarkdale does change that a bit. Intel has finally delivered an integrated graphics solution that is at least competitive with existing IGPs on the market. To show you how far it’s come I’ve pitted our Clarkdale based Core i5 661 against an AMD Phenom II X4 965 with 790GX graphics. Our 790GX platform had 128MB of on-board memory to drive performance even higher. If Intel can manage a win here, it'll be a convincing one.

I’ve also tossed in a G45 board for good measure. The only absent member is NVIDIA's GeForce 9400. We found in our 790GX review that AMD delivered roughly the same graphics performance (if not better) as the 9400 so any advantage/disadvantage here would apply to NVIDIA as well.

We’ll start off with Batman: Arkham Asylum. This is an Unreal Engine 3 based game. The first thing you need to remember about integrated graphics is that regardless of the game, you’ll want to go in and turn down every single quality setting at your disposal. In this case I ran Batman at 1024 x 768 with all quality options set to low.

That's Batman running on Intel HD Graphics

Batman doesn’t look half bad at the playable IGP settings. It’s surprising. Tim Sweeney once told me that a good looking game is half engine, half art. It looks like Batman just has that right combination of engine and art to make it look decent even on Intel’s integrated graphics. It’s not great by any means, but it’s not pixelated mush.

The performance is also halfway respectable. Intel’s fastest integrated graphics manages to tie AMD’s 790GX IGP at 35 fps. It’s also over twice as fast as G45. Even the lower end Core i3 CPUs should manage close to 30 fps here.

Next up is Dragon Age. Unfortunately, this game doesn’t look as good at its playable integrated graphics settings. It ends up looking like 3D Kings Quest played on a PS2.


Dragon Age Origins - Integrated Graphics Performance

Performance is respectable from the new Intel HD graphics. At 41.5 fps it’s actually faster than AMD’s 790GX chipset. Definitely more than twice the speed of the old G45. Keep in mind that we’re looking at the highest end IGP from Intel. The Core i3s will be appreciably slower, most likely at or below the performance of the 790GX.

Dawn of War II on Intel HD Graphics

Dawn of War II looks and plays like crap on Intel’s integrated graphics. Averaging 15 fps on the fastest Clarkdale, the minimum frame rates dropped as low as 3.4 fps. This is a huge improvement over G45, but definitely not what I would consider playable.

Intel is technically the leader here though. AMD’s 790GX only managed 12.1 fps. IGPs need not apply for this title at present.

Call of Duty Modern Warfare 2 is the first time that we see Intel losing. The game loses much of its visual appeal at the settings you need to run at in order to be playable on integrated graphics, especially on a larger screen.

Call of Duty MW2 - Integrated Graphics Performance

AMD’s 790GX is around 40% faster than Intel’s HD Graphics. Blech.

World of Warcraft is a very important title to perform well under and unfortunately Intel loses this one to AMD. However, we are running at the "Good" setting as opposed to bare minimum detail settings:

Our final integrated graphics game benchmark is HAWX.

HAWX - Integrated Graphics Performance

At 53 fps Intel falls behind the 790GX but it’s around 2x the speed of G45 and high enough that I’d consider it playable (albeit at the lowest possible settings).

Intel has taken a significant step forward with its integrated graphics. It's at the point where I'd say it's finally competitive with the best from AMD or NVIDIA. Intel has delivered on its promise to take integrated graphics more seriously, and I hope we will see even bigger performance gains with Sandy Bridge.

Intel took a big step forward to the point where it is no longer the laughing stock of the graphics industry. But it stepped into a position of mediocrity, joining AMD and NVIDIA. Integrated graphics has never been good regardless of the manufacturer. We honestly need to be at around 2x existing performance to deliver a reasonable gaming experience on integrated graphics. AMD is going to be shipping its 8-series chipsets later in the year and perhaps that will change things.

Idle Power Consumption - Integrated Graphics

Despite the 45nm on-package GPU, the Core i5 661 actually draws more power at idle than the old G45 with an E8600. It's still much more power efficient than the equivalent from AMD. If you're building something with integrated graphics, you want it to be a Clarkdale.

To test power consumption under load I fired up a 1080p x264 video using Media Player Classic Home Cinema and measured total system power consumption:

Load Power Consumption - Integrated Graphics

A CPU swap and some tweaking later and our AMD power consumption numbers now make sense. While playing H.264 encoded video the GPU does all of the heavy lifting and there's no power advantage for Clarkdale to rest on. When watching a movie the AMD system is indistinguishable from our Clarkdale test bed.

    Indeed, I want an Atom+ION, but it has not yet come to public availability in Brazil. And Intel is killing ION with the new Atoms, so I believe I won't ever see a Atom+ION board here, because the stores will only launch only the "newer" Atom boards (that is, IF they even launch it...) Reply

    The other problem with and atom setup is the low cost no L3 cache Athalons. With a decent 785G mainboard, you can get much better performance in only a slightly bigger package for about the same HTPC money. That is the direction I would go if I could build an HTPC right now. Reply

    The reason for high idle and in some way, high load power is due to the Asus board. Not only that, but the H57 chipset.

    The Intel H55 mobo will lower power consumption enough to get it below the i5 750 and i7 860.

    Would these be chips on would dare to overclock considering the foxconn socket problems that has been reported here @ anandtech? Reply

    Its quite confusing now, with 9 desktop and 11 mobile i-xxx cores now. Not a single digit shows core numbers or the gpu on the new 32nm cpus.
    Actualy its a total mess now for a average user.

    I second your opinion!!! Perhaps Intel hired some marketing folks from Nvidia!!! =D Reply

    So which chip is responsible for HDMI Audio - the CPU, or the H5x chipset?
    Can we get HDMI audio support with a Lynnfield CPU?

    And one other thing - I assume we can use HDMI audio without haeving to use the integrated GPU (for display) when we have a PCI-E card?

    The GPU on the processor. Reply
  • Alberto - Monday, January 4, 2010 - link

    The main problem is the Motherboard, likely an early sample not much optimized. Both Xbit Lab and The Tech Report have found a lower idle system power consumption in the new Intel plataform versus the Lynnfield solution. Maybe This article needs of a fast update :-) Reply

    The italian site have discovered even better results. Over an Intel DH55TC motherboard this new cpu is IMPRESSIVE at idle.
    Intel seems right again.
