However, the Xbox has the advantage of 10 MB of eDRAM. In terms of bandwidth, the PS3 slightly edges out the Xbox. The PS3 has 256 MB of dedicated video RAM in addition to being able to share up to an additional 224 MB from the system RAM. The Xbox's Xenos card features more video RAM, but this RAM is shared with the console's system RAM. ![]() The verdict: Both the Xbox 360 and PS3 rely on custom-designed graphics cards. Up to 512 MB GDDR3 RAM (shared w/ system RAM)Ģ56 MB GDDR 3RAM (additional 224 MB can be shared w/ system RAM) This new combined chip may edge out the PS3's CPU in terms of reliability and temperature control, but no long term tests have been performed yet. But in order to ensure proper functionality, Microsoft was forced to install a "frontside bus replacement block" that introduces latency and forces the chip to run at the same speed as the older model. Interestingly, the new combined CPU/GPU chip used in the new Xbox 360 is theoretically faster than the individual chips in older models. And in terms of performance measured in gigaflops, the PS3 tops out at nearly three times that of the Xbox. The two CPU chips run at the same GHz speed, but the PS3's seven individual cores beat out the Xbox's three dual-threaded cores. Note – Gigaflop performance numbers determined by The verdict: The processors for the Xbox and PS3 are unique enough in their respective architectures that it can be difficult to make direct comparisons. This throwdown is based on the most recent versions of both consoles – the 'Slim' variations of both the Xbox 360 and the PlayStation 3, disregarding previous feature sets.ħ single-threaded cores (plus 1 backup core) ![]() In the end, only one system can emerge victorious. We've broken the console war into ten technical categories, including CPU, GPU, hard drives and so on. We've decided to examine the war from a technical perspective, comparing which system sports more power under the hood and which offers a superior set of features.
