Summary: Sapphire has been making some of the best ATI-based video cards for a while, and the Sapphire 4850 X2 is no exception. The board is well constructed, and the heatsinks are better than what you expect for OEM.
Summary: When looked at from a pure performance standpoint, then the Sapphire HD 4850 X2 is among the top cards on the market. It beats the NVIDIA GeForce GTX 280 by about 3%. What is also very interesting is that in higher resolutions the HD 4850 X2 can also beat the bigger brother, the HD 4870 X2.
Pros: Great performance, Lots of overclocking potential left, Better average performance per Dollar ratio than GTX 280, Beats HD 4870 X2 in high resolutions, DirectX 10.1 support
Cons: Extremely noisy card, CrossFire does not work in windowed 3D, Hot air not exhaust out of the case, Complex overclocking process, Dual GPU design - depends on optimum driver support, Long PCB, No support for CUDA/PhysX
Summary: Sapphire have done extremely well with their Toxic HD4850, and by including a pre-installed, all copper Zalman VF900 cooler, they have successfully addressed the issue of excess heat from the original Radeon HD4850.
Summary: Sapphire's HD4850 is very similar to MSI's R4850 both in terms of performance and speed. Well, it's not surprising as both cards are based on AMD/ATI's referernce designs. In all of our benchmarks the peformance was very good. No complaints here.
Conclusion: It was a real shame that it wasn’t possible to compare any cards to the 4850, as in terms of bang for buck, we haven’t seen anything this good since the 8800GT last year. It may not be the cheapest card around, but it’s performance for the money is great.
Pros: Good performance, Great bang for buck, Quiet, Single slot cooler
Conclusion: Suorituskyky kortilla on testin parhaimmistoa lukuun ottamatta sähkönkulutusta, jossa kortti on yllättäen selvästi tehonälkäisempi kuin Club3D:n vastaava kortti. Sapphirella on hieman korkeammat kellotaajuudet m ...
