See Amdahl's law
Quantum processors will do little for games.

Ok, so we have the cloud computing model, we know that we can take a calculation and spread it around to an infinite number of processors to get the same job done in less time. While the idea of running a game over a network is ridiculous, what's to say you can't run the same type of system on a single chip with package management fast enough to get the numbers out the door before the user notices?

(Yes, most of this is way over my head. I'm just trying to have a bit of conjectural fun here.)

Why is it so hard for some to understand more cores is the future.Period. Just look back at the last 10 years,going from single to hyperthreaded,dual then quad cpus.What is Intel's top performing chip? A 6 core 12 thread chip. What will be nVidia and AMD's top performing card? A dual GPU solution. It really is not that hard to figure out.

Read the link he posted and it will become clear.

Sadly, people will see '16 cores' and think it's amazing, irrespective of actual performance.

lol if i saw a 16 core processor, id still say wow wouldnt you? dont hate on consoles just because its cool here on OCN to do it

Not all calculations can be split up like that. Multithreading (efficiently and safely) is some of the most difficult programming there is, IMO.

Take, for example, the following calculation: 2 + 2 * 3. There are two operations here, an addition, and a multiplication. However you would gain nothing from multithreading this, as you can't do the addition until you have the result of the multiplication. It's an inherently linear calculation. There are all kinds of things that cannot be broken up, or cannot be broken up easily or efficiently.

I'm not asking for a massive in-depth explanation but don't you need the 2+2 to be calculated before you multiply? Are you not multiplying the result of 2+2? Oh, right BEDMAS. So, what are you then multiplying? If 2+2 has not yet been calculated, then what are you multiplying by 3?

Except that not all code can take advantage of many cores. It has remained quite a challenge to write code to take advantage of more than a couple cores, look how long we've had dual and quad core processors on the market, ~5 years, and still there are only a few types of programs that you see really taking advantage of and scaling with those extra cores.

With new materials, like graphene, we may yet still see clock speed improvements and of course there are always IPC improvements to be made as well. Many cores is a part of our future yes, but not the only part.

You said it yourself- BEDMAS (PEMDAS). Multiply 2 * 3 first, then add it to 2.

but ATM it still looks like my sig rig will out game coming gen of console, redface.gif

Just because the game won't use all of them, you have dedicated to other things, such as kinect like was stated in the article. "multitasking" tongue.gif
