    Playstation 4 - top secret alien technology

    Okay out of the 15 replies, I count 5 negatives, and no positives. I'm guessing Americans aren't crazy for Playstation 4. That'll change once it is actually unveiled on February 20 - 2 weeks from today.

    Playstation 4 - top secret alien technology

    HA. You can tell this is the year 2013 - when 1080p gaming is no longer cool, but 2560x1440 is. I.e. everyone's into technology - highly unusual. That was the joke. Soon - "1080p is passé, 2160p is the new in."

    Playstation 4 - top secret alien technology

    I helped design it. I studied the alien technology, being a scientist working in top secret missions. Seriously though - very advanced. 20 years ahead of all other hardware. What does this mean for you? Well - it has Windows-like OS support. So the person will be able to surf the web...

    The CPU memory bandwidth problem

    Yes but you're not exactly taking the best CPU from every 2 years and then comparing it to the previous - most of those are centered after 2005. Only the Pentium 2 is in 1998. But yes it is has doubled that fast - for that app.

    The CPU memory bandwidth problem

    At this rate, in 100 years, that Intel chip will be 100 times more powerful then the Pentium 4 HT. This seems a little slow.

    The CPU memory bandwidth problem

    On a different note - these processors are not advancing as fast as I thought they were. It's a completely linear increase. Every year - it increases by the same amount X. Thus since 2004 - it has increased by approximately the strength of the Pentium 4 HT, every year, in performance. Thus 9...

    The CPU memory bandwidth problem

    I would postulate that the Pentium 4 660 would give 1/4 the performance of the Intel i7 3770K. But it in fact gives 1/10th the performance. Why - the i7 3770K has 8 MB of L3 cache - the Pentium 4 660 doesn't. Thus - the L3 cache makes a difference. If not for that - it would be 1/4th. The...

    The CPU memory bandwidth problem

    The memory bandwidth has only tripled on Intel's CPUs since 2004, a space of 9 years. The Pentium 4 HT Extreme supported 8.512 GB/s of memory bandwidth, while the latest Intel Core i7 Extreme Edition only supports 25.6 GB/s...

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    The Pentium 4 Extreme Edition's maximum memory bandwidth was 8.512 GB/s. It was released in 2004: http://ark.intel.com/products/27492/Pentium-4-Processor-Extreme-Edition-supporting-HT-Technology-3_73-GHz-2M-Cache-1066-MHz-FSB The second generation Core i7 Extreme Edition (the latest Intel...

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    This also allows for far greater optimization of the memory - which is key. As the memory problem is the main problem. A regular computer: CPU A few hundred registers 8 MB of L2 cache 512 Kbytes of L1 cache An external memory bus A bus to the GPU GPU 512 - 4 GB of DDR5 RAM A separate bus to...

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    It's far more power efficient. It makes the computer smaller. You don't even need a separate graphics chip on the motherboard, let alone another video card.

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    However the 12-15 times greater general purpose-processing will open the door of possibilities. Greater A.I. performance, more characters (playable and non-playable), and better physics. This generation had very small numbers for all of those.

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    Okay new information. Apparently the Bobcat is a 380 million transistor processor, with just 2 cores. Why - the on-chip GPU, 80 32-bit SIMD units. However - the Jaguar will not have that. It will have a separate SIMD unit. So it's hard to tell how many transistors the Bobcat is actually...

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    According to IBM they are both based on the Power4 architecture. Just an interesting side-note. Why's that? Basically the same hardware - similar pipeline, clock-speeds, and transistor size. It simply uses half the execution units - except for the VMX. They took the Power4 and modified it.

    Digital Foundry: next-gen PlayStation and Xbox to use AMD's 8-core CPU and Radeon HD

    Upon close examination - mine only shows PCMark. Your shows that one, and others. But your PCMark one is an average of all 6 - mine show all 6 separately. I didn't look at all of the individual marks. So it turns out - the different benchmarks do agree - the Brazos is better in all 6...
