[Hexus] Samsung starting production on 8GB of GDDR5 @ 20nm

Sounds like Sony might like this for a future revision of the PS4. Not to boost clockspeeds, but to run cooler and save power.

Thats one of the least likely possible options.

Thats one of the least likely possible options.

And why's that?

 

[ShintaiDK]

And why's that?

Because they rather buy the cheaper one every single time.

Remember this is a premium product.

Sure, so they wouldn't hop on it immediately But down the road, especially when they're looking to make a PS4 Slim? They'll do it.

Is that because its 20nm or that it'll hit speeds up to 8Gbps, cause if its the latter then surely there must be low performance GDDR5 chips From Samsung even at 20nm :|

Guys this is mostly to reduce the cost of it and up the speed a bit for the same power consumption.

I think this will be good for entry level and mid range GPU's for the next year, while we still have all of the top end GPU's using GDDR5 memory, so HBM is still ways off and we are probably talking mid 2015 until it becomes standard for top end hardware and late 2015 before it starts tricking down to mid level graphics.

I think overall its positive and will reduce memory costs a bit in 2015, while also offering a bit more performance. So we are going to see a bit cheaper entry level and mid level graphic cards.

Because its 8Ghz. Top bins, highest cost.

Nonetheless, they could use chips from the same process.

Those that can get to 8GHz can be sold to graphics card vendors. Those that only clock to 5500MHz can be sold to Sony. Because the ceiling is 8GHz, your chances of getting a chip that can clock at 5500Mhz will be pretty high, which should help lower costs.

Yup. It's not like they will only have 8000Mhz high-density options. It's more or less a given that Sony will move to higher density GDDR5 at some point in its life cycle. It's also a given that those APUs from MS and Sony will be shrunk to lower nodes, which was one crucial advantage of going with a unified APU from AMD in the first place over say an Intel + NV dual chip combo where realizing cost savings from lower nodes was not guaranteed.

Am I the only breed of nerd that thinks it's kind of hot? And first hearing about HBM, feeling like I'm in a threeway?

Yeah. I'm not in the slightest turned on by computer hardware.
