After TahitiXT Radeon HD7970 to the market December 22 last slide which is the Fastest single GPU, AMD released the Radeon HD7950 Tahiti Pro Her sister still uses the same chip "Tahiti" with a new architecture GCN (Graphic Core Next), which distinguishes the best silicon wafer into TahtiXT whereas the central part of the edge into Tahiti Pro, are still using TSMC 28nm fabrication process, Tahiti Pro Had to be placed against the GTX580 because we know the Radeon HD7970 tighter range of 20%.
Laser cut with TahitiXT who have 32CU (compute units) 28CU just trimmed it to his sister Tahiti Pro and the decline in core clock and memory clock, this will impact performace decrease 15-17% slower than the HD7970. AMD provides the option for free to pertnernya cooler design is usually the beginning of the emergence of the Radeon HD7950. This time we get a sample version of the Sapphire HD7950 OC with 3GB Dual Fan.
OC Version for designing Sapphire Radeon HD7950 uses a non-reference cooler. With 2 big size 12cm fan this fan will cool the GPU Radeon HD7950 chip which inherits TahitiXT we know its a predatory OC.
In the product positioning AMD Radeon HD 7950 puts it slightly below or above HD7970 HD6970 to compete with competitors GTX580.
Sapphire HD7950 Overclock Edition is a version of the factory with a 100MHz core clock 9000MHz or higher than the AMD reference to 1250MHZ memory clock (5000MHz Effective) unfortunately not in the OC out of the box when we are familiar with Hynix chips have an insane OC potential, Sapphire seems to want to provide "gap" in order not to overlap with the performance of his elder brother Radeon HD7970.
Design non reference cooler with a blue PCB and cooling solution from Sapphire uses two sizes 12cm fan looks beautiful. The cooling system is similar to the Radeon HD6970 Dual Fan is very effective to reduce GPU heat with the noise level is SILENCE.
Already using PCI-E 3.0 Sapphire HD 7950 requires two slots in cooler.
To turn on Sapphire HD7950 OC is required 2x6 pin PCI-E which 500Watt PSU recommendation rating 80 plus. With a strong performance AMD GPU with the successful design of low power but high performance.
Sapphire HD7950 is equipped with dual bios like the reference from AMD, we see the bios switches 1 and 2, it is quite helpful when a corrupt bios switched live to the bios 2.
Sapphire HD7950 OC to have connectivity:
1 x Dual-Link DVI
1 x HDMI (with 3D)
2 x Mini-DisplayPort
DisplayPort 1.2
Sapphire display typical of his box a sexy girl with ruby ruby theme being plunged into battle. Bundle that came with the Sapphire quite luxurious fittings:
CrossFire ™ Bridge Interconnect-Cable
DVI to VGA Adapter
Mini-DP to DP cable
6 PIN to 4 PIN Power Cable x 2
HDMI to DVI Adapter SL-
HDMI 1.4a high-speed cable 1.8 meters
To answer our curious how fast the Sapphire HD7950 OC Edition, we want to include the GTX580 but in the absence of the VGA we include "old Fermi" to think thought GTX480 Sapphire HD7950 OC Edition's performance of this, we need to know in general GTX480 performace same / similar to the GTX570 or 15% slower than GTX580, but it's probably not fair that we can serve to increase the "hot" testing. For comparison we also include the Sapphire HD7970.

The most interesting part of the chip is Ocnya Tahiti that we knew it was crazy, this time we were curious about the extent to which OC headroom of Sapphire HD7950 OC Edition. With the program we were able to reach Sapphire ThriXX core / memory 1185/1801MHz (Effective 7204MH) is safe for gaming with a vCore 1.275v this is really crazy, especially its memory OC is "crazy 7.2GHz"
