    Yes, anyone have any knowledge on the differences?

    I would definitely consider upgrading to the 4 GB in these 4K/5K times, but I'm not confident that the 460 is offering higher performance over the 455 beyond that.

    Specs are on AMD's website, the 2015 R9 M370X is 80GB/s memory bandwidth and 1.3TFflops 2GB memory, the Radeon Pro 455 is 1.3TFlops 80GB/s memory, the Pro 460 is 1.85TFlops and 80GB/s memory bandwidth.


    Apple a few months back said teaming up with AMD's new Polaris architecture would yield console class performance on the MacBook Pro... indeed they achieved this, the Radeon Pro 460 at 1.8TFlops is the same exact performance as a 3 year old Playstation 4, congrats Apple. Only down side is its not console class now as the PS4 Pro is 4.2TFlps and the Xbox Scorpio is 6TFlops.

    Wait, what? The Radeon Pro 455 is the same as the old R9 M370X?

    According to AMD its exactly the same, 1.3TFlops and 80GB/s memory bandwidth.

    I'm walking away today not being disappointed at all with the new MBP's. I do really want TB3 and USB-C but the negatives outweigh the positives, Ill keep my maxed out mid 2015 till the next update.

    Spec for Spec to match a mid 2015 with the cpu, gpu, and HDD space, its $2999, I only paid $2800 a year and a half ago, whats the deal Apple.

    What settings can they run Witcher 3 on?

    Say it in a way I can gauge where we are lol.

    Compared to what we had before, wouldnt either one of these be able to run 90% of games at high settings?

    Yes

    The increase in GPU is from the 460 not 450

    Witcher 3 is a pretty hard game to even run well on decent desktop components, if you the yummy visuals turned on.

    lol they had a chance to jump aboard the superior nvidia chipset, and have a real winner on their hands. oh well.

    Probably low/medium at 1080p, and no. They really chose a pretty gimped selection of GPUs - the 1060 would have been the money choice, but I guess they'd rather keep holding the grudge against nVidia for past failures and pass the angst onto customers.

    :Edit: Looks like if the desktop RX460 part is any indication, it averages 41fps on High@1080p. Note that the laptop part will probably be clocked lower and I'd say medium-high (note High is not maxed, there's a step or two above it into Ultra territory) at 1080p, but gaming at 1080p on a MBP is pretty rough as there are bars on the top and bottom of the 16:10 screen and you're obviously not near native res. You'll have to go case by case on if games support 16:10 resolutions and if not you'll probably be able to force 1920x1200.

    Not super ideal, to be honest, but not terrible.

    Based on similar performing GPU's as the radeon pro 460 to hit the 60 fps sweet spot would be medium at 1080p, big step down into the 40 fps range to get into the high detail range, and unusable 20 fps at ultra.

    I think the PS4 has a better cooling system, I doubt if the 460 in the MacBook Pro can really match the old PS4 in real world (due to thermal throttling) :D

    Oh most definitely, I think Linus Tech Tips just did an video on uselessly watercooling a PS4, even on stock air it maintains 70C and no thermal throttling, a MBP barely manages to stay under 98C under load and throttling like a fool.

    The 1060 has a much higher TDP...

    This is definitely true, but in terms of performance they aren't on the same charts.

    Wow, that's incredulous. I was literally ready to throw $3,000 at Apple for a new machine, but I just can't justify it for these extremely minimal spec bumps, gimmick features, and huge price increases.

    Take a look at these benchmarks, according to my research, the Pro 460 is conparable to the GTX 965M

    Until I see a benchmark of the EXACT Radeon pro 460 I think it's not wise to compare it to anything. We just don't know yet is the truth

    It's worth the upgrade. Even if it's a minor core/clock boost, you are doubling the video memory. I would suggest this upgrade over any CPU upgrade, especially the 6770->6820 (a whopping 5% increase!).

    M375X = 450 <= 455 <= 460 is where the M375X from last generation falls, based on Gflops.

    455 is just under the performance profile of the nvidia 960M, and the 460 is just under the 965M. So if you look at benchmarks for those cards, you should be within a reasonable ballpark.
