Xbox One's memory performance has been hugely underestimated
We were previously told that the ESRAM could handle around 102 GB a second. The real maximum figure could be as high as 192 GB a second - no inconsiderable jump. I'm going to lapse into both direct quotation and technical jargon now, so if that kind of thing rubs you the wrong way, skip to the second pair of scare quotes.
"According to sources who have been briefed by Microsoft, the original bandwidth claim derives from a pretty basic calculation - 128 bytes per block multiplied by the GPU speed of 800MHz offers up the previous max throughput of 102.4GB/s," reads the piece.
"It's believed that this calculation remains true for separate read/write operations from and to the ESRAM. However, with near-final production silicon, Microsoft techs have found that the hardware is capable of reading and writing simultaneously. Apparently, there are spare processing cycle "holes" that can be utilised for additional operations.
"Theoretical peak performance is one thing, but in real-life scenarios it's believed that 133GB/s throughput has been achieved with alpha transparency blending operations (FP16 x4)."

That's what I thought, Sony is doing an amazing job on the PS4 :D
Both consoles look great imo.
Yeah, I agree. It's going to be hard to choose.(for me)
I'm getting the Xbox One because I'm more familiar with the Xbox 360 so the Xbox One shouldn't be too much of a difference, plus I also don't want to restart my whole profile over.

Too bad without the memory the games won't work properly >_> Even your profile requires memory to work as well.
I know, but do you really think the PS4 won't have enough space for a profile?
you never know man ;p
Haha, it will probably have enough space for 10,000 profiles! :D
maybe a million :0
That would be too much, I doubt a million.
