Brilliant game developer says Microsoft cloud computing does not appear to give the Xbox One a significant edge

Gaming legend and id Software Technical Director/cofounder John Carmack at his QuakeCon 2013 keynote offered up his thoughts on Microsoft Corp.'s (MSFT) Xbox One and Sony Corp.'s (TYO:6758) PlayStation 4, which will be waging war this holiday season for dominance in the eight generation of home video game consoles.

He led off by saying that he hadn't done enough head to head benchmarks to make direct comparisons between the consoles.  But based on his experience (Mr. Carmack still remains actively involved in programming top id Software titles and pioneering new graphics techniques) he says he believes they're "very close" in capabilities and that "they're both very good".

In some ways this comparison is bad news for Microsoft as it calls into queston the company's claims that its console is five times as powerful when connected to the cloud as when processing offline (if anyone would fully leverage the Xbox One's full potential, it would likely be Mr. Carmack).

Also bad news for Microsoft is Mr. Carmack's dour assessment of the Kinect sensor.  Aside from concerns regarding "always on" U.S. National Security Agency (NSA) spying (Microsoft has a major voluntary data sharing agreement with the NSA, reportedly), Mr. Carmack offers criticism of the controls themself, stating, "[The Kinect 2 is] kind of like a zero-button mouse with a lot of latency on it."

The PS4 appears to enjoy a moderate lead in preorders over the Xbox One.

For the unitiated, you may ask why listen to Mr. Carmack.  Well, he coded a hardware-optimized build of Wolfenstein 3D for the iPhone in 4 days, when it was estimated to take a full team of programmers two months to perform a basic (unoptimized) port.

You're also talking a newer, faster clocked version of the same cores with just fewer compute units. In this case the GPUs are 100% the same, just fewer units.

Now yes 50% more compute units does not translate into 50% faster performance.

Here is a good kind of "benchmark" to show the kind of real world differences between the chips:

Performance difference is pretty small here. In instances of high framerate you get about a 10 frame difference, and in low framerate about 2~4. Overall a 19% to 24% difference according to digital foundry. Doesn't take into account the cache/memory differences in both consoles either. Less DRAM throughput on the xbox but very fast low latency ESRAM, while the ps4 has high gddr5 throughput but no fast cache outside of CPU L2.

I'm inclined to believe Carmack here since he was able to deliver pretty similar performance on the ps3 even with a less than stellar memory config compared to the 360 for Rage, so clearly he isn't one to lose performance for the sake of simplicity or fanboyism.

And you call that "pretty small"?? In an era where people fork over hundreds of dollars for 10 more FPS in a video card, I would say that's pretty significant.

I don't know about that. 7870 ghz is $209 and the 7850 is $159 on newegg (both from sapphire). That's about 15~25% more performance there for fifty dollars more. Go up to the 7950 and you start looking into 40~70% territory depending on resolution for a hundred fifty more.
