Xbox One's memory performance has been hugely underestimated

4.6
The Xbox One Messaging Carnival continues with the discovery that Microsoft may have underestimated the new console's technical prowess, according to a report published by Digital Foundry. Citing a number of Xbox One developers, the site claims that the machine's embedded static RAM may crunch almost twice as much data a second as initially suggested.

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)."

Aggie Maybe they should have started out with this instead of all the Crap application.


Ikr -.- I hate microsoft so much..

-Live They are either changing the hardware or they gave out false tech specs. I'm thinking false tech specs because it would be disatrous to change hardware that late before the consoles release but that could be why the console had so few console pre-order slots.

This is good, atleast they are making they're **** faster but it would make the consoles about identical now except for having DDR3 RAM in there, they may say they had GDDR5 ram later too but I don't know.


Spoken like a true person that has no idea.

They never gave out false information, they just didn't know that with further testing the silicon could perform better than they'd hoped. As for changing to gddr5, no, just no.

Jerkingit I don't get it


If Im correct, it the higher that number is the faster and smother the xbox one can read and process games. so sense its sooooo high, so much shit can happen during a game.?

xDiLL Everyone is underestimating the Xbox One.


Well they did it to themselves, they sold their product short.

And this is why the unit process's 3 OS at the same time this much raw power per second is incredible especially for what the system is running simultaneously!

People said the Xbox One will be terrible. I can't wait until it's out.
