BioShock: Infinite

Bioshock Infinite is Irrational Games’ latest entry in the Bioshock franchise. Though it’s based on Unreal Engine 3 – making it our obligatory UE3 game – Irrational had added a number of effects that make the game rather GPU-intensive on its highest settings. As an added bonus it includes a built-in benchmark composed of several scenes, a rarity for UE3 engine games, so we can easily get a good representation of what Bioshock’s performance is like.

BioShock: Infinite

Both the 650M and desktop GT 640 are able to outperform Iris Pro here. Compared to the 55W configuration, the 650M is 32% faster. There's not a huge difference in performance between the GT 640 and 650M, indicating that the performance advantage here isn't due to memory bandwidth but something fundamental to the GPU architecture.

In the grand scheme of things, Iris Pro does extremely well. There isn't an integrated GPU that can touch it. Only the 100W desktop Trinity approaches Iris Pro performance but at more than 2x the TDP.

BioShock: Infinite

The standings don't really change at the higher resolution/quality settings, but we do see some of the benefits of Crystalwell appear. A 9% advantage over the 100W desktop Trinity part grows to 18% as memory bandwidth demands increase. Compared to the desktop HD 4000 we're seeing more than 2x the performance, which means in mobile that number will likely grow even further. The mobile Trinity comparison is a shut out as well.

    I see Razer making an Edge tablet with an Iris-based chip. In fact, it seems built for that idea more than anything else. That or a NUC HTPC run at 720p with no AA ever. You've got superior performance to any console out there right now and it's in a size smaller than an AppleTV.

    So yeah, the next Razer Edge should include this as an optional way to lower the cost of the whole system. I also think the next Surface Pro should use this. So high end x86-based laptops with Windows 8 Pro.

    And NUC/BRIX systems that are so small they don't have room for discrete GPU's.

    I imagine some thinner than makes sense ultrathins could also use this to great effect.

    All that said, most systems people will be able to afford and use on a regular basis won't be using this chip. I think that's sad, but it's the way it will be until Intel stops trying to use Iris as a bonus for the high end users instead of trying to put discrete GPU's out of business by putting these on every chip they make so people start seeing it CAN do a decent job on its own within its specific limitations.

    Right now, no one's going to see that, except those few fringe cases. Strictly speaking, while it might not have matched the 650m (or its successor), it did a decent job with the 640m and that's a lot better than any other IGP by Intel.

    You confused me here on these points:

    1) The NUC uses a 17W TDP chip and overheats. We're not going to have Iris in that form factor yet.
    2) It would increase the cost of the Edge, not lower it. Same TDP problem too.

    Otherwise I agree, this really needs to roll down lower in the food chain to have a serious impact. Hopefully they'll do that with Broadwell used by the GPU when the die area effectively becomes free thanks to the process switch.

    So intel was right. Iris Pro pretty much matches a 650m at playable settings (30 fps +). Note that anandtech is being full of BullS**t here and comparing it to an OVERCLOCKED 650m from apple. Lets see, when intel made that 'equal to a 650m' claim it was talking about a standard 650m not an overclocked 650m running at 900/2500 (GDDR5) vs the normal 835/1000 (GDDR5 + boost at full, no boost = 735 mhz core). If you look at a standard clocked GDDR3 variant iris pro 5200 and the 650m are pretty much very similar (depending on the games) within around 10%. New Intel drivers should further shorten the gap (given that intel is quite good in compute).

    For the games I tested, the rMBP15 isnt' that much faster in many titles. Iris isn't quite able to match GT 650M, but it's pretty close all things considered.

    I will believe this about new Intel drivers when I see them. I seriously, genuinely hope they surprise me, though.

    Are you going to test this system with madVR?
  • Ryan Smith - Sunday, June 2, 2013 - link

    We have Ganesh working to answer that question right now.

    Cool. :)

    I would have liked to see some madVR tests. It seems to me that the particular architecture of this chip - lots of computing power, somewhat less memory bandwidth - would be very well suited to madVR's better processing options. It's been established that difficult features like Jinc scaling (the best quality) are limited by shader performance, not bandwidth.
    The price is far steeper than I would have expected, but once it inevitably drops a bit, I could see mini-ITX boards with this become a viable solution for high-end, passively-cooled HTPCs.
    By the way, did they ever fix the 23.976 fps error that has been there since Clarkdale?

    Missing Remote reports that 23.976 timing is much better.
