The closer formal announcements dates of next-generation game consoles are, the more rumours about possible performance and capabilities of Microsoft Corp.’s Xbox Next and Sony Corp.’s PlayStation 4 “Orbis” start to emerge. According to some data from anonymous game developers, Sony’s future console may be considerably more powerful than Microsoft’s.
Sony PlayStation 4 “Orbis” will feature raw compute power of around 1.84TFLOPS, whereas Microsoft Xbox Next (code-named Durango or Loop) will only be capable of 1.23TFLOPS, according to “developer sources” of VG247 web-site. In case the information is correct, the PlayStation 4 will be around 50% faster, based on pure compute performance, than the Xbox Next.
Considering the given numbers, it is unclear whether developers compared peak compute performance of graphics processing units, central processing units, or total compute performance of next-gen consoles.
While pure number of floating point operations per second (FLOPS) does not necessarily result into more realistic graphics or higher quality of game play on game consoles (PS3 is much more capable than X360 when only GFLOPS are considered, in the real-world the difference is negligible), 50% difference is just too high to ignore, considering alleged architectural similiarities between the two forthcoming platforms. For example, in the world of graphics processing units for PCs 50% difference in TFLOPS usually points to different classes of graphics processors; those classes have significantly dissimilar levels of real-world performance and which prices are incomparable (e.g. AMD Radeon HD 7850 with 1.76TFLOPS vs. AMD Radeon HD 7770 with 1.28TFLOPS).
Given supposed architectural similarities of PS4’s and Xbox Next’s architectures, it is highly unlikely that raw compute performance difference between the two will be around 50%.
Both Microsoft Xbox Next (Durango, Loop, 720, etc.) as well as PlayStation 4 (Orbis, Odin, Omni, etc.) are projected to be based on custom microprocessors and graphics processing units developed by Advanced Micro Devices and largely based on PC hardware. It is expected that both consoles will be available this holiday season for $350 - $400.
Microsoft and Sony did not comment on the news-story.
