The Wrong End Of The Telescope – Is HSA still AMD’s future?

If so, how does this work with AMD’s upcoming high-end Summit Ridge CPU’s? It is widely accepted that HSA does not deliver on its promise (at least under current architecture) if there is not a tight coupling of the CPU and GPU with a shared memory allocation, and also affected by latency problems with PCIe. Hence, i can buy a £300 laptop which supports HSA, but I cannot build a PC that leverages the power of my £600 graphics card and £300 CPU. Either they sort out this limitation of shared memory pool and latency over PCIe, they stick shaders on Summit Ridge, or, HSA has no part to play in their high-end offerings.

At least that is what I used to think, but perhaps I have been looking through the wrong end of the telescope.

AMD has confirmed that they won the WiiU – What about the Xbox720 and PS4?

Q – Why do consoles massively outperform their PC equivalent hardware?

A – Because they use a streamlined software stack and optimised hardware.

Let’s ignore the former for it doesn’t tell us anything interesting, for while every real console (i.e. not ouyu), will seek optimised software and hardware only the latter will help us with the big questions. Consoles are machines specifically designed to pump out graphics so the determining factor will be the GPU, and from a console vendors perspective what is the prime consideration when choosing a GPU?

Price/performance. A combination of the number of transistors and their clock speed.

3D Vision Surround And The Survival Of PC Gaming – Nvidia joins the party.

In the previous article this blog looked at ATI’s multi-screen Eyefinity technology for gaming, stating that it was an example of the platform innovation that will keep PC Gaming healthy even against the rise of the Console, well now Nvidia has joined the party with its 3D Vision Surround, a combination of Nvidia’s 3D stereographic gaming technology with multi-screen gaming.

With the two major graphics chip vendors on board we can hope for broad support for multi-screen gaming in all major games releases.
