請教各階顯示卡的時脈?& BIT?
最近想升級DX9的顯示卡
爬文又看得霧殺殺 就近請教各位 各階顯示卡的時脈?& BIT? FX5700=時脈?& BIT? FX5900=時脈?& BIT? 6600=時脈?& BIT? 6600GT=時脈?& BIT? |
FX 5900 GPU:256bit
你是指5900NU的話 核心400MHz 記憶體時脈850MHz Memory Interface 256Bit FX 5700 GPU:256bit 核心 425MHz 記憶體時脈600MHz Memory Interface 128Bit 6600 GPU:256bit 核心 300MHz 記憶體時脈500~550MHz Memory Interface 128Bit 6600GT GPU:256bit 核心 500MHz 記憶體時脈1GHz Memory Interface 128Bit |

感謝二位
撇開6600GT來說 FX 5700 GPU:256bit 核心 425MHz 記憶體時脈600MHz Memory Interface 128Bit 6600 GPU:256bit 核心 300MHz 記憶體時脈500~550MHz Memory Interface 128Bit 看來FX 5700 比6600來得優勢嚕? 那跨一階的6600怎還輸給FX5700呢? 他會比5700優越性在那裡? 不就買FX5700就可了?懇請賜教........... :D |
表面上規格如此,還有一些是大家忽略的規格
GeForce FX 5700 Memory Quantity 128MB Chip NVIDIA NV36 Core Clock Speed 425MHz Memory Speed 250MHz Theoretical Performance (@425MHz) Pixel Fill-rate 1700M Pixels/sec Texture Fill-rate 1700M Texels/sec AA Sample Fill-rate 3400M Samples/sec Geometry-rate 170M Vertices/sec Memory Bus Bus Width 128-bit Crossbar 2x64-bit Memory Bandwidth 8.0GB/s Memory Type Support DDR Rasteriser Basic Pipeline Config 4 / 4 / 4 Textures / Pixels / Z Samples Per Clock Textures Per Pass 16 Filtering Per Texture Unit Bilinear Filtering Methods Bilinear, Trilinear, 8X Anisotropic Texture Compression DXTC (1-5), S3TC Fragment Processing PS2.0 Extended Fragment Pipe Precision FP16, FP32 Fragment Pipe Config 1 Full, 2 Small FP ALU's per pipe |
GeForce 6600

GeForce 6600..........................GeForce FX 5700 Chip NVIDIA NV43.....................Chip NVIDIA NV36 Core Clock Speed 300MHz..........Core Clock Speed 425MHz Memory Speed 275MHz..............Memory Speed 250MHz Memory Bandwidth 8.8GB/s.........Memory Bandwidth 8.0GB/s Basic Pipeline Config 8 / 4 / 8......Basic Pipeline Config 4 / 4 / 4 很多看不懂........ :ase 比較之下了代號差異(NV43 &NV36代號差異會有很大的效能差別嗎?) 大致差距好像會很大嗎? 而核心時脈大於6600的5700會優越性在那裡? . . 就優越性該選那個好? |

最白濫的算法,300*8>425*4,所以6600贏過5700 |
6600 and 5700 核心架構不相同,
不能單以時脈來相比, 選的話當然是 6600 好嘍...:P |
6600主要是在於硬體上架構略多於5700,Geometry-rate是6600優於5700的地方,其他其實差不多,見仁見智啦。這種用過才知道,我只能說商業導向很重.....
