128 Bit CPUs - AnandTech Forums
网页2012年1月16日 · Current CPUs have 128-bit memory controllers or greater, but many low end cpus and graphics cards use less, as low as 32-bit. The size of mathematical calculations the cpu can do. The x87 extension to the x86 instruction set made cpus capable of 80-bit precision a long time ago. SSE can do 128 bit.
Why 64bit consoles? - AnandTech Forums
网页2005年11月19日 · The 128-bit CPU is the first of its kind in the world, integrated with the state-of-the-art 0.15 micron process technology on a single LSI. The new CPU incorporates two 64-bit integer units (IU) with a 128-bit SIMD multimedia command unit, three independent floating point vector calculation units (FPU, VU0, VU1), an MPEG 2 decoder …
ddr 3 64 bit vs ddr 2 128 bit - AnandTech Forums
网页Jul 9, 2010. #13. bryanW1995 said: @overlordi: 128bit vs 64 bit means nothing, it's the total bandwidth that matters. the 4350 is 20.8 gb/s while the 4650 is 25.6 gb/s. ddr3 is faster than ddr2, but not enough to make up for that kind of difference.
Ryzen's halved 256bit AVX2 throughput - AnandTech Forums
网页2017年3月9日 · All in all it's a neat core with solid efficiency and Intel is likely to follow a somewhat similar path in consumer to gain efficiency. x264 shouldn't be using 256b. It's half the throughput of its competitor. Also, the number of AVX2 enabled programs continues to increase, along with the level of optimization.
1x256bit CPU or 4x64bit, whats the impact - AnandTech Forums
网页2001年9月20日 · For non-SIMD integer math, having a 64-bit CPU vs. a 32-bit CPU doesn't imply that the 64-bit CPU is twice as fast. SISD arithmetic (single instruction, single data) operates on two operands and yields one result; if you do 1 + 1, it doesn't matter if you express the numbers with 32-bits or 64, the instruction will still do only one add.

Info LPDDR6 @ Q3-2024: Mother of All CPU Upgrades
网页2022年4月1日 · Clearly you have underestimate the impact of LPDDR6. I am mostly referring to PC market, with 64-bit memory bus LPDDR6, OEMs could design smaller SoC with the memory bandwidth of past 128-bit LPDDR5X. By removing half of memory pin connector, OEMs like NV could design SoC with Xbox series S's graphics performance …
Discussion AMD's Future CPU-APU Gone ARM - AnandTech Forums
网页2024年2月19日 · Since DDR6 is delayed, NVL-S will support 128-bit DDR5. Based on timings, it should support up to DDR5-8000. And that might be the speed AMD would use to support Zen 6C, that's mean AM5 platform will live for another generation.
Info LPDDR6 @ Q3-2024: Mother of All CPU Upgrades
网页2024年5月22日 · M3 Pro getting gutted to 192 bit might be the first step... (Speculation) M5 : 96-bit LPDDR6 M5 Pro : 192-bit LPDDR6 M5 Max : 384-bit LPDDR6 it makes sense, because LPDDR6 will adopt 24-bit memory channels, which is a 50% increase from LPDDR5/5X. This means the traditional 128/256/512 bit memory buses are not possible.
