Sapphire’s card is based upon the Juniper Pro chip, manufactured on TSMC’s 40nm fabrication process. The number of transistors on the new chip is 1.04 billion with a die size of 170mm2. The chip has 720 Stream Processors, which is exactly ½ that of the Radeon HD 5850. There are 32 texture units on the HD 5750 and 64 Z/Stencil units.

The key feature of the HD 5xxx series is the support for DirectX 11 and OpenGL 3.1. Microsoft released Windows 7 on the 22nd of October and is being installed on millions of computers worldwide as we speak. The new OS is the first to feature DirectX 11 as the graphics API for games which features Tessellation, Compute Shaders, Multi-threading on games HDR texture compression and Order independent transparency as the main features.

Eyefinity is the new multi-monitor technology that ATI developed in the course of developing the HD 5xxx series. The HD 5750 can drive up to three monitors using Eyefinity to have a wider field of view playing games like RPGs, Flight Simulation games and FPS games. The technology is also useful for those wanting to look at a lot of screen space like a stock trader that needs as much information as quickly as possible.

Sapphire has put their Vapor-X technology on the HD 5750 card I’m reviewing today. Sapphire recently revealed that their Vapor-X technology uses Microloops technology which is a company in Taiwan. Vapor-X uses the same principle as a heatpipe. A liquid coolant (water) is vaporized at a hot surface (the GPU), the resulting vapor is condensed at a cold surface then the liquid is returned to the hot surface via a wick system. This keeps the card cooler than a standard 5750 under load. Under load a maximum temperature of 56C has been noted even overclocked. This is an excellent result for a video card as the clock on the overclock was over 850MHz.
