Battlefield 3

Our multiplayer action game benchmark of choice is Battlefield 3, DICE’s 2011 multiplayer military shooter. Its ability to pose a significant challenge to GPUs has been dulled some by time and drivers at the high-end, but it’s still a challenge for more entry-level GPUs such as the iGPUs found on Intel and AMD's latest parts. Our goal here is to crack 60fps in our benchmark, as our rule of thumb based on experience is that multiplayer framerates in intense firefights will bottom out at roughly half our benchmark average, so hitting medium-high framerates here is not necessarily high enough.

The move to 55W brings Iris Pro much closer to the GT 650M, with NVIDIA's advantage falling to less than 10%. At 47W, Iris Pro isn't able to remain at max turbo for as long. The soft configurable TDP is responsible for nearly a 15% increase in performance here.

Iris Pro continues to put all other integrated graphics solutions to shame. The 55W 5200 is over 2x the speed of the desktop HD 4000 and the same for the mobile Trinity. There's even a healthy gap between it and desktop Trinity/Haswell.

Ramp up resolution and quality settings and Iris Pro once again looks far less like a discrete GPU. NVIDIA holds over a 50% advantage here. Once again I don't believe this is memory bandwidth related, Crystalwell appears to be doing its job. Instead it looks like fundamental GPU architecture issue.

The gap narrows slightly with an increase in resolution, perhaps indicating that as the limits shift to memory bandwidth Crystalwell is able to win some ground. Overall, there's just an appreciable advantage to NVIDIA's architecture here.

The iGPU comparison continues to be an across the board win for Intel. It's amazing what can happen when you actually dedicate transistors to graphics.

    Even for a given power usage the 650M isn't even to on the top of the list for highest end discrete GPU.... The top at the moment for lowest wattage to power ratio would be the 765M, even the Radeon HD 7750 has less wattage and a tad more power than the 650M. Clearly someone did not do their researching before opening their mouth.

    I'm gonna go out on a limb and say that vFunct is one of those Apple fanboys that knows nothing about performance. You can get a PC laptop in the same size and have better performance than any Macbook available for $500 less. Hell you can even get a Tablet with an i7 and 640M that'll spec out close to the 650M for less than a Macbook Pro with 650M.

    The Iris Pro 5200 would be ideal for both machines. Pro users would benefit from ECC memory for the GPU. The Iris chip uses ECC memory making it ideal for OpenCL workloads in Adobe CS6 or Final Cut X. Discrete mobile chips may produce errors in the OpenCL output. Gamers would probably prefer a discrete chip, but that isn't the target for these machines. Reply

    I think Apple cares more about the OpenCL performance which is excellent on the Iris. I doubt the 15" will have a discrete GPU. There isn't one fast enough to warrant it over the Iris 5200. If they do ever put a discrete chip back in, I hope they go with ECC GDDR memory. My guess is space savings will be used for more battery. It is also possible they may try to reduce the display bezel. Reply

    It's never had the highest end chip, just the best "upper midrange" one. Above the 8600m GT was the 8800m GTX and GTS, and above the 650m there was the 660, a couple 670 versions, the 675 versions, and the 680.

    They chose the highest performance part that hit a specific TDP, stretching a bit from time to time. It was generally the case that anything which outperformed the MBP was either a thick brick, or had perpetual overheating issues.

    It wouldn't surprise me if the 15in just had the "beefed up" iris pro honestly. They might even get their own, special even more overclocked than 55w version.

    Mainly, because it wouldn't be without precedent. Remember when the 2009 15in macbook pro had a 9400m still? Or when they dropped the 320m for the hd3000 even though it was slightly slower?

    They sometimes make lateral, or even slightly backwards moves when there are other motives at play.

    That's just crazy talk, they want drop dedicated graphics. The difference is still too big, plus you can't sell a $2000 laptop without a dedicated GFX. Reply

    considering Apple specifically asked for eDRAM and since there is no dual core version yet for the 13", I'd say there is very good chance. Reply

    "The difference is still too big"

    The difference in what?

    Something tells me Apple and its core market is more concerned with rendering/compute performance more than Crysis 3 performance...

    If it plays Crysis 3 well, it can render/compute/do whatever intensive fine. Reply

    Nvidia Kepler plays Crysis 3 well but it sucks insanely hard at computing and rendering. Reply
