RDRAM was controversial during its widespread use by Intel for having high licensing fees, high cost, being a proprietary standard, and low performance advantages for the increased cost. RDRAM and DDR SDRAM were involved in a standards war. PC-800 RDRAM operated at 400 MHz and delivered 1600 MB/s of bandwidth over a 16-bit bus.
An early version of RDRAM, base RDRAM, was used in the Nintendo 64 that was released in 1996. [24] Disadvantages of RDRAM technology include significantly increased latency, power dissipation as heat, manufacturing complexity, and cost. PC800 RDRAM operated with a minimum latency of 45 ns, compared to 15 ns for PC133 SDRAM.
The Intel 850 supports 16bit RIMM of PC600 or PC800, and the memory bandwidth reached 3,2 GB/s when using PC800 RIMM (Rambus Inline Memory Module). This is three times the memory bandwidth of 1,06 GB/s of PC133 SDRAM, which was the mainstream in the previous generation, and matches the bandwidth of 3,2 GB/s of FSB of QDR 400MHz adopted in ...

Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
The Alpha 21364A was to have improved upon the Alpha 21364 by featuring higher clock frequencies in the range of ~1.6 to ~1.7 GHz and support for 1066 Mbit/s RDRAM memory. It was to be fabricated by IBM in their 0.13 μm silicon on insulator (SOI) process. As a result of the more advanced process, there were reductions in die size, power supply ...
RDRAM was a proprietary technology that competed against DDR. Its relatively high price and disappointing performance (resulting from high latencies and a narrow 16-bit data channel versus DDR's 64 bit channel) caused it to lose the race to succeed SDR SDRAM.
