DDR Standard In High-End 3D For A While
Of course, DDR-SDRAM is really not that new at all. It was pretty much introduced in the mainstream-PC arena by NVIDIA almost a year ago. NVIDIA's GeForce 3D-chip was one of the first PC-components that worked with DDR-SDRAM and since this time there is hardly any high-end 3D-card that could do without this memory type anymore. However, it took a while longer until all the specifications for DDR-SDRAM as main memory were finalized.
The Memory Industry Gives Broad Support
Due to its free and open specification , DDR-SDRAM enjoys a broad support in the memory industry. Right now we know of eight different memory makers that are already producing DDR-SDRAM DIMMs in all kinds of sizes.
| Memory Maker | DIMM Sizes |
|---|---|
| Hitachi | 64 MB, 128 MB, 256 MB |
| Hyundai | 64 MB, 128 MB, 256 MB, 512 MB |
| IBM | 64 MB, 128 MB, 256 MB, 512 MB |
| Infineon | 64 MB, 128 MB, 256 MB, 512 MB |
| Micron | 64 MB, 128 MB, 256 MB, 512 MB |
| Mitsubishi | 64 MB, 128 MB, 256 MB |
| NEC | 64 MB, 128 MB, 256 MB |
| Toshiba | 64 MB, 128 MB, 256 MB |
DDR-SDRAM gets manufactured in a very similar way as normal SDRAM, which is why there won't be much of a price premium for the new memory type.
| Memory Type | Clock Specification | Price |
|---|---|---|
| PC100, 128 MB, CL2 | 100 MHz | $110 |
| PC133, 128 MB, CL2 | 133 MHz | $116 |
| PC200 aka PC1600, 128 MB, CL3 | 100 MHz DDR | $116 |
| PC266 aka PC2100, 128 MB, CL2 | 133 MHz DDR | $125 |
