Sony has been praised by several developers for their decision to include of 8GB of GDDR5 RAM in their upcoming next generation console, the PlayStation 4. The faster memory apparently gives more budget to developers to render out high resolution textures and free up other resources for game development. There have been numerous reports that the PS4 has 50% more raw power than the Xbox One, and new reports seem to back those claims.
According to Nick Baker, who looks after the Xbox One’s architecture team believes that GDDR5 is uncomfortable to work with and ESRAM gives the Xbox One the right balance for bandwidth and power consumption.
“In terms of getting the best possible combination of performance, memory size, power, the GDDR5 takes you into a little bit of an uncomfortable place. Having ESRAM costs very little power and has the opportunity to give you very high bandwidth. You can reduce the bandwidth on external memory – that saves a lot of power consumption as well and the commodity memory is cheaper as well so you can afford more. That’s really a driving force behind that. You’re right, if you want a high memory capacity, relatively low power and a lot of bandwidth there are not too many ways of solving that.” he said in an interview with EuroGamer.
