76.8GB/s of memory bandwidth in 2004

[LoveGuRu]

this is a really good thread, althogh i dont undertand anything you write, its not every day you find a thread that people talk about things you are not close to understand.
thogh this is a step forward towards understanding more, just wanted to thank Raystonn fos starting this thread.

Observation:

Even though "Yellowstone" is classified as ODR it doesn't opperate as such. It is really DDR at 1066MHz. Double data rate at a high frequency. So does that mean that DDRSDRAM at a higher clock could beat the "Yellowstone" RDRAM? It would seem so due to the lack of number of latencies inherent in DDR and the lower overall total latency in DDR vs. RDRAM per clock.

Mala, even 2 or 3 cycles lost in sending the data request to the northbridge can be huge performance killers, especially if the cpu is sitting idle for that data!

T-RAM. A potential SRAM/DRAM replacement. A 1 transistor memory cell, no capacitors, but instead uses a thyristor. Looks like it could be what's coming, depending how hard it is to manufacture. I spotted this while browsing the AT forums.

Who knows with this kind of thing maybe on die RAM seems a little closer.

I was going to start my own thread, but I missed this one.

<i>i read that hammer is gonna have an integrated onboard northbridge... that should improve memory interface bandwidth and latencies</i>

This is the approach SUN takes with the UltraSPARC III (and earlier) with the memory controller on the CPU die. It allows them to add a large external L2 cache (8MB for the US3) and get excellent performance out of the memory.

integrated memory controller, not norhtbridge.

It's not what they tell you, its what they don't tell you!

Seems to me Raystonn was rather conservative, not optimistic.

Quote: "T-RAM is a semiconductor startup that is developing a unique type of memory that combines the speed of SRAM with the density of DRAM. T-RAM is compatible with mainstream CMOS processes, using only standard equipment and standard materials, and the performance of logic transistors remains unaffected."
