These modules usually combine multiple chips on one circuit board. SIMM modules connect to the computer via an 8-bit- or 32-bit-wide interface. RIMM modules used by RDRAM are 16-bit- or 32-bit-wide. [49] DIMM modules connect to the computer via a 64-bit-wide interface. Some other computer architectures use different modules with a different bus ...
Thus, Intel describes a 20-lane QPI link pair (send and receive) with a 3.2 GHz clock as having a data rate of 25.6 GB/s. A clock rate of 2.4 GHz yields a data rate of 19.2 GB/s. More generally, by this definition a two-link 20-lane QPI transfers eight bytes per clock cycle, four in each direction. The rate is computed as follows: 3.2 GHz
Further, a "cumulative clock rate" measure is sometimes assumed by taking the total cores and multiplying by the total clock rate (e.g. a dual-core 2.8 GHz processor running at a cumulative 5.6 GHz). There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus , the latency of the memory ...
Common clock rates for these processor links are 800 MHz to 1 GHz (older single and multi socket systems on 754/939/940 links) and 1.6 GHz to 2.0 GHz (newer single socket systems on AM2+/AM3 links—most newer CPUs using 2.0 GHz). While HyperTransport itself is capable of 32-bit width links, that width is not currently utilized by any AMD ...
In computing, the clock multiplier (or CPU multiplier or bus/core ratio) sets the ratio of an internal CPU clock rate to the externally supplied clock. This may be implemented with phase-locked loop (PLL) frequency multiplier circuitry. A CPU with a 10x multiplier will thus see 10 internal cycles for every external clock cycle. For example, a ...
The RL78 family is an accumulator-based register-bank CISC instruction set architecture (ISA). [2] Although it has eight 8-bit registers or four 16-bit register pairs, essentially all arithmetic operations are performed on a single accumulator (the A register or AX register pair).
