MSI R5830 Twin Frozr II
The 5830 is more or less a 'crippled' 5850/5870, it has the same GPU but has three out of the ten clusters of shader processors disabled.
The older Radeon HD 4850/4870/4890 had 800 shader processors while the new 58xx lineup has up to 1600 shader processors (AKA stream processors).
Here's an overview of the 58xx line-up:
- Radeon HD 5830 has 7x 160 Shader clusters = 1120 Shader processors
- Radeon HD 5850 has 9x 160 Shader clusters = 1440 Shader processors
- Radeon HD 5870 has 10x 160 Shader clusters = 1600 Shader processors
What does the Twin Frozr II edition bring us when compared to the reference 5830?
- A better Thermal Design.
- Military Class Components
- voltage is up to 1.35V
There is no performance difference in-between the reference product and the MSI R5830 Twin Frozr II, but it will probaly be a better overclocker.
Conclusion:
Bringing the 5830 down to seven shader clusters with a total of 1120 shader processors and cutting the accumulated color ROP engines in half, sixteen instead of
thirty-two, slow down overall performance significantly, when compared to the 5850/70, but nevertheless it still is an interesting product. It's probably the best 5830
around, with a great overclock potential, that is if you use the AfterBurner OC software with voltage regulation.
Overclocking:
The reviewer OCed this card from 800 MHz to 928 MHz, and the memory from 4000 MHz to 4800 MHz. That's a 15-20% performance increase, which is quite a lot.
Benchmarks:
Battlefield: Bad Company 2, Metro 2033, Just Cause 2, Call of Duty Modern Warfare 2, Colin McRae DiRT2, Resident Evil 5, Far Cry 2, Crysis WARHEAD, Tom Clancy's HAWX, Anno
