Tips Dan Trik Seputar Dunia Komputer

AMD belum secara resmi mengumumkan apa pun berkaitan dengan seri Radeon HD generasi berikutnya. Kita tahu bahwa seri terbaru tersebut akan datang, tetapi belum ada informasi resmi pada model, spesifikasi atau kecepatan clock dari AMD.
Tapi kadangkala informasi itu telah bocor terlebih dahulu, dan berikut ini ada bagan yang telah bocor dari dua sumber yang berbeda menunjukkan lompatan kinerja yang akan datang dari Radeon HD 6700 series bernama “BARTS”. Informasi ini  belum dikonfirmasi, tapi kita tentu berharap bahwa informasi tersebut benar, mengingat klaim perbaikan kinerja yang signifikan.


Seperti beberapa kutipan dari www.gnd-tech.com dijelaskan sebagai berikut :
The 6750 clearly offers more compute performance, being at 1.624 TFlops compared to 1.360 TFlops on the 5770. The core clock however is lower at 725 MHz, compared to 850 MHz on the 5770. The 5770 offers 800 stream processing cores while the 6750 has 1120, which is the same as the 5830. The amount of texture units has been increased from 40 to 56 (56 is the same as the GTX 460), leading to a nice texture fill rate increase from 34 GTexel/s to 40.6 GTexel/s. This is also higher than the GTX 460 which has a texture fill rate of 37.8 GTexel/s. Pixel fill rate has increased from 13.6 GPixel/s to 23.2 GPixel/s, which is faster than the GTX 460's 16.2 GPixel/s. It has 32 ROPs, 8 more than the GTX 460 768 MB. The 6750 also has a memory clock of 1000 MHz (4000 MHz effective data rate) leading to a memory bandwidth of 128 GB/s. This is higher than the 5770's 76.8 GB/s and it's higher than the GTX 460's 86.4 GB/s. In fact, it's higher than the GTX 460 1GB which has a memory bandwidth of 115.2 GB/s. The 6750 has a TDP (thermal design power) of only 116W. Much lower than the GTX 460's 150W rating. Impressive card here that's for sure.

Moving up to the 6770, which once again is supposed to compete against the GTX 460 1GB, we see even more impressive specifications. The core clock has been bumped up to 900 MHz, compared to 850 MHz on the 5870 and 725 MHz on the 5850. Unfortunately it only has 1280 stream processing cores compared to the 1440 on the 5850. This may not look good at first, but the 6770 does have a compute performance rating of 2.304 TFlops compared to 2.088 TFlops on the 5850. Texture fill rate has also gone up from 52.2 GTexel/s to 56.7 GTexel/s, which is much higher than the GTX 460's 37.8 GTexel/s. There are 64 texture units - 8 more than the GTX 460 and 8 less than the 5850. Once again it has 32 ROPs (same as GTX 460 1GB) and a pixel fill rate of 28.8 GPixel/s. This is clearly higher than the 5850 which is 23.2 GPixel/s. It's also higher than the GTX 460 1GB which is 21.6 GPixel/s. The memory clock has been increased to 1050 MHz (4200 MHz effective data rate) leading to a memory bandwidth of 134.4 GB/s which is higher than the 5850's 128 GB/s and higher than the GTX 460 1GB which is rated for 115.2 GB/s. The TDP for the 6770 is said to be 146W, which is less than the GTX 460 1GB which is rated for 160W.


Nah, bagaimana dengan NVIDIA???Kali ini NVIDIA kembali memperkenalkan produk barunya yaitu GeForce GT340.
