利用较为准确的Sandra memorybenchmark测试内存的带宽、潜伏性能中,可以比较轻松的看出DDR3内存在Int(整型)和Float(单精度浮点运算)带宽比DDR2的带宽提升明显,这也主要得益于DDR3内存预读8bit的优势。 SiSoftware Sandra2009延时测试 在Sandra memorybenchmark测试内存延时项目中,可以看出DDR3内存延时控制非常高,均在100n...
Many factors affect system performance, and memory speed is just one of those factors. Since the results for high-end memory were so close at all tested speeds, the scale range was reduced to better show the small differences in these memory benchmark results. Please keep this in mind when...
Posted in Memory 27 Comments Crucial PC2-6400: Gaming Performance Several games were chosen to help determine the stability of Crucial's Ballistix DDR2-800 memory: Quake 4 was used, set to ultra quality, and benchmarked with results in frames per second (FPS) at 1024x768, 1280x1024, and...
通过WinRAR测试,我们看到一个1GB的高分辨率图片文件夹在不同频率下压缩时间是不同的,在DDR2-800频率是,用时为4分09秒;而DDR3-1333频率用时为3分57秒,相比DDR2-800少用12秒。 ●孤岛危机2 在孤岛危机2测试中,笔者采用的是游戏自带的Benchmark测试,然后取三遍测试成绩的平均值。游戏分辨率:1680*1050 孤岛危机...
Here the G.Skill DDR2 runs just behind the Geil memory at overclocked speeds, stock speeds give an even result. G.Skill and OCZ tie it up for the win here at overclocked. Benchmarks - Prey Prey Version and / or Patch Used:1.2 ...
Sure enough, here is a graph showing SiSoft Sandra "Memory Bandwidth" benchmarks for various memory speeds in single- (1x 1GB DIMM) and dual-channel (2x 1GB DIMM) setups: [/img] As you can see, observed dual-channel memory bandwidth is the same from DDR2-533 to DDR2-800, due to...
1、DDR内存 DDR完整的应该称DDR SDRAM,但是就是习惯称为DDR,SDRAM 是“Synchronous Dynamic Random Access Memory”的缩写,也就是“同步动态随机存取存储器”的意思。而DDR SDRAM是Double Data Rate SDRAM的缩写,是“双倍速率同步动态随机存储器”的意思。 内存的发展趋势,从DDR->DDR2->DDR3->DDR4。 2、GDD ...
但是everest memory benchmark發現copy頻寬大跌...似乎不是好事呢;smash;E eric680507 初級會員 已加入 7/24/08 訊息 3 互動分數 0 點數 0 7/24/08 #19 如果以單純記憶體來看的話 1200會不穩,1280穩定 那是有可能的...這個屬於IC的關係,有些IC對高壓敏感 有些對低敏感(意思就是 有的高壓FAIL 有...
Considering the fact that PCMark runs a series of read, write, copy and latency tests with varying load of 16 MB to 4KB, this score is quite impressive. We also ran Everest memory benchmarks and got a score of 5904MB/s read, 4849MB/s write and 5372MB/s copy speed with a DRAM: ...
You could then use a couple of different memory dividers, whatever works with your combo, but at least you would be able to see the real difference big DDR2 memory speeds make to overall performance. You also need to show some stability benchmarks. There's no use having memory that can...
