AMD Radeon HD 5770 and HD 5750 Review - Juniper and DX11 for all
The Evergreen Blossoms again
The train of new graphics cards keeps rumbling by with another stop at the AMD headquarters. On September 23rd we saw the release of the AMD Evergreen-based graphics card, the Radeon HD 5870, that was followed up exactly a week later by the Radeon HD 5850 that offered the same feature set with slightly lower performance and a slightly lower price.
AMD is impressing us again with yet another new graphics release pulling the Evergreen architecture even lower in price. This new GPU was known as Juniper and is physically a new die spin, not simply a Cyprus core with some additional cores disabled. The new Radeon HD 5770 and Radeon HD 5750 that we are reviewing today again breath new life into both AMD and the PC gaming market.
The New Radeon HD 5770 and HD 5750
First, let me say that we aren't going into the gory details of the Evergreen GPU architecture in this review - if you have yet to read up on it or need a refresher, please head over to our Radeon HD 5870 review where we go into some good detail on what has changed in the move from the 4000-series to the new 5000-series including DX11 support, improved computing power and of course the popular Eyefinity technology.
As I mentioned, the Juniper-based GPUs are a completely new GPU spin based on the Evergreen design. Here is a diagram of this new GPU:
Both Juniper GPUs consist of 1.04 billion transistors; less than half the count of the Radeon HD 5800s.
As we go over in detail in our HD 5870 review, there are some new features that make the HD 5000-series of GPUs stand out from the 4000-series:
- Support for DirectX 11 and Shader Model 5.0
- Support for OpenCL 1.0 (and likely OpenCL 1.1)
- Angle independent anisotropic filtering (finally!)
- "Nearly free" 4xMSAA
- Very low idle power consumption
- AMD Eyefinity multi-monitor gaming - first performance testing here
- Three monitor support on a single card
