Introduction

On 12th of July 2010 NVIDIA introduced new graphic cards supporting DirectX 11.GeForce GTX 460 are based on GF104 GPU of Fermi architecture which are produced using 40nm technological process:

Compared to GF100 new GPU (GF104) has an improved parallel computing technology called Thread Level Parallelism, which theoretically can significantly boost GPU performance. The number of Dispatch Units and LD/ST blocks for single Streaming Multiprocessors (SM) is doubled compared to GF100:

As a result of such innovations, now SM can process four instructions per clock, while GF100 processes only two operation at the same time.

High-end Fermi models, based on GPU GF100, were introduced back in spring and now NVIDIA releases two GTX 460 models of middle-end segment. The top GeForce GTX 460 model features 1Gb ofGDDR5 video memory. The other GTX 460 has reduced to 768Mb amount of video memory, therefore, memory bus with has been cut down from 256-bit to 192-bit. Moreover, number of ROPs interrelated with memory interface and Level 2 cache has been brought down by 8.
In this review, we will get acquainted with Zotac SYNERGY GeForce GTX 460 768Mb [ZT-40401-10P] graphic card.

Technical specification

Performance config and clocks of Zotac SYNERGY GeForce GTX 460 768Mb are the same as reference design GeForce GTX 460 768Mb has:

Since GTX 460 768Mb has less memory and as a result crippled performance config, its memory interface bandwidth suffers too. According to official specification Texture Fill Rate of GTX460 is between GTX 480 and GTX 470:
