![]() It lacks out-of-order of execution and the smaller cores lack branch prediction. The architecture of the Cell is much more basic than a typical x86 one. High performance is typically achieved by streaming data into it. This means everything the smaller core runs has to fit on its 256 KB of local memory. ![]() The main core can feed the smaller ones though. Data goes in and out of them between each other than through the main core. The main restriction of the smaller cores is they cannot directly access memory. It then has 8 (or 7 in the PS3's case to I prove yields) smaller cores that are not like a traditional CPU core. The Cell is comprised of one core that more or less looks like a traditional CPU core. So while you might point out that this makes the Cell more powerful, you have to understand its architecture and how it can achieve that performance. Based on what I can scour on the internet, the commonly stated performance for the Jaguar in the PS4 is ~100 GFLOPS. Since there's no direct comparison I'm aware of between the two, the only thing I can go off of is the rates GFLOPS rating, which Sony claimed the Cell can achieve ~230 GLFOPS. ![]() It's the same why clock frequency alone isn't a good indicator of performance. Does the cpu of the playstation 3 have 8 cores and that of the playstation 4 the same? What is the most powerful CPU?Ĭores count alone isn't a very good indicator of performance.
