On the issue of GPU performance

So here. Consider all gigaflops, the number of fans, shader processors and others. And I am the owner of a modest HD5450. I bought it so that the computer was noisy and less electricity was consumed.

And here is my surprise: there are only 16 stream processors (5x VLIWs), but now, by mistake, I launched two instances of Dead Space 2, and they mistakenly started (usually Windows applications check the common Mutex to run in a single copy), and both went at the same time - almost without brakes (I play in window mode, so I could see). And you say: Fermi. Dead Space 2 is not the most unpretentious toy, there are a lot of moving objects, rather complicated “monsters” that sometimes fall out on a player in large quantities, shadows, play with light. However, the same works! Whether the matter is in the art of programming, or in optimizing compilers for shaders. This means that all these APUs and SoCs may well be igro-capable with their rather compact GPUs on board, which, in addition, due to the lack of the need to copy data from memory to memory and because of the higher frequency, can be more productive than the HD5450. In general, I was surprised, among other things, with the fact that programmers decide.
