Uh, actually kergeten many PC games (including Crysis) are extremely well optimized for GRAPHICS CARDS. RAM is a whole different beast, and a completely uncomparable process as RAM is used for more than running games on PCs.
Not all PC games are well optimized, but Crysis is one that is, and it can't be run on max without at least an 8800GT. The PS3 runs a modified 7800GT. It would run it on medium at 30 FPS and 720p at best. There would most likely be signifficant slowdown too. The PS3 is certainly good at some things. The Cell is great for physics operations. In many ways better than any current CPU, but its graphics card is severely lacking compared to those in modern PCs.
Sorry kergeten, but you really don't know what you're talking about. |
One thing the Cell is great at, other than doing physics on its own w/o needing the GPU to do it, is figuring out what it doesn't have to send to the GPU at all, thereby sparing the GPU that load as well. Example: the Cell SPE's absolutely fly when asked to determine which polygons are on the back surfaces of figures, and therefore don't have to be drawn by the GPU. Cell (all because of the SPEs) blows away Pentiums and the Xenon at this...so while other GPUs are busy drawing polygons, many of which won't be visible to the player in each frame, RSX won't have to be doing that nearly as much IF a game is optimized well for Cell. Cell, more than Intel/AMD/Xenon processors, can increase the power of the GPU it is paired with, especially considering the insane bandwith between the two when compared to PC setups. So, your 8800GT vs. 7800GT analysis neglects a lot. |
It is usually assumed that people realize that the 8800gt is powerful enough on its' own to handle the graphics workload. And im sure that the floating point advantage of the PC GPU can more than compensate for the SPE's on the cell if you wanted to battle em or something. Don't forget that a humble Core 2 duo @ 3ghz packs quite the punch in integer operations |
Re: 1st bolded statement: But is it recognized that RSX isn't as "weak" as a 7800GT used in a PC for a PC game?Re: 2nd bolded statement: I'm confused about your switch from discussing GPU/floating to discussing Core 2/interger in those 2 sentences, but anyway. Issue is, how much can certain advantages of Cell, with optimized code, make up for a GPU that is eclipsed by top-end GPUs in PCs -- considering that no PC setup is as uniform or optimized-for, so there is more hardware power wasted in PCs -- as well as Windows eating up tons of resources. I'm not saying that Cell makes PS3 better than high-end PCs, I'm just stating what I think are some reasons not to say "7800gt |
A more accurate assessment is that the 8800gt is more than twice as powerful as the RSX, partially due to efficiency gains between the generations. :) For this reason, Crysis won't do better than medium-high at 720p. You also have ram constraints and such which make the system less efficient in spite of optimization. Optimizations aren't all at no cost, sometimes you have to tradeoff one feature for another. On consoles this has generally been due to a lack of RAM.
The PS3 isn't weak, it's SOLID. Unfortunately it can only fall behind PC's further and further, with the next round of cards coming later this year, One TFLOP won't be uncommon for a mid-high end single GPU card.
