тише, тише друзья - не воспламеняйтесь так раньше времени
вот вам на разогрев про мощь SONY
Digital Foundry: Let's talk about next-gen console. What's your take on the general design in terms of CPU and graphics processing power?
Oles Shishkovstov: We are talking PS4, right?
I am very excited about both CPU and GPU. Jaguar is a pretty well-balanced out-of-order core and there are eight of them inside. I always wanted a lot of relatively-low-power cores instead of single super-high-performance one, because it's easier to simply parallelise something instead of changing core-algorithms or chasing every cycle inside critical code segment (not that we don't do that, but very often we can avoid it).
Many beefier cores would be even better, but then we'll be left without a GPU! With regards the graphics core, it's great, simply great. It's a modern-age high-performance compute device with unified memory and multiple compute-contexts.
The possibilities of CPU-GPU-CPU communication are endless, we can easily expect games doing, for example, AI pathfinding/route planning executing on GPU to become a common thing.
Digital Foundry: To what extent is the 8GB of GDDR5 in the PlayStation 3 a game-changer? What implications does that have for PC, where even the standard GTX 680 ships with just 2GB of GDDR5?
Oles Shishkovstov: RAM is really, really important for games, but all of it actually being useful depends on available CPU-side bandwidth and latency to the external storage device. I think that they put slightly more RAM than necessary for truly next-generation games this time, but considering the past history of
Sony stealing significant percentage of RAM from developers for OS needs - that may be exactly the right amount!
ну и главный подарок
Digital Foundry: Do you think that the relatively low-power CPUs in the next-gen consoles (compared to PC, at least) will see a more concerted push to getting more out of GPU Compute?
Oles Shishkovstov: No, you just cannot compare consoles to PC directly.
Consoles could do at least 2x what a comparable PC can due to the fixed platform and low-level access to hardware.
Back to the question - yes, yes and yes. There are some things which are just more efficient to do on massively parallel machines like GPUs are. I think that at least initially, with launch titles, the GPU-Compute will be underutilised, but during console's lifetime we'll see more and more unbelievable and innovative things purely thanks to GPUs.
ждем подкаста и прихода Амедея-Себастьяна БАБАХа
