Sapphire Dual-X R9 270
Forms cards look very familiar, similar to the R7 265 Dual-X. Combinations between black and gray medium gray on the mask to keep the quality of a product gaming, creat a luxurious feel to the product.
Black paint looked very smooth, flattering and eye similar to the metal material. Without their fingers will try hard to realize the mask is made of plastic.
Dark brown water darkening circuit. This is my favorite circuit board color, look both beautiful and hard-to medium. The blue tones, green, light brown … inappropriate for the graphics card. The length of the circuit board is quite reasonable: long enough to evoke card seems sturdy, but not too long causing heavy volume pressure the slot and also not to difficult installation and wiring in the chassis cheap.
Kindness welded components, circuit board tidy. Next to each component are annotated letters should be looking at the back of the eye vessels scattered enjoyed, feeling very thick density components.
Sapphire R9 270 Dual-X only requires one 6-pin auxiliary power as the ref of AMD. As far as I understand, the R9 270 is rename the HD 7870 (two 6-pin auxiliary power). 1 GPU but use the same power supply is limited to many, worries me overclocking capability of the product will be less than the HD 7870.
Sapphire R9 270 Dual-X is equipped with two DVI, one HDMI and one DisplayPort connectors. With 4 ports, users can export up to 3 screens at the same time very convenient for both gaming and work.
Circuit Board looked quite familiar. Not only radiator, R9 270 Dual-X also employs the latest motherboard design with R7 265 Dual-X. GPU is equipped with 4 power phases. Quality components with DrMOS FDMF 6823C and solid capacitors Japanese .
R9 270 Dual-X also uses memory chips codenamed H5GO2H24AFR Skhynix. 8 memory chips are cooled by the thermal pad excellent exposure.
2 large heatpipe heatsink, cooling performance is very good as we all know. The aluminum foil is processed meticulously, all eight episodes straight. The only minus point is the heatpipe are not plated with nickel, over time will inevitably be stained.
Accessories come relatively complete including manuals, driver disk, DVI-DSUB port, Molex supplementary power cable – 6 pin and in particular the CrossFire bridge again.
Sapphire card is set at 945/1400 MHz pulse – a little mild overclock compared to the standard version of AMD.

Overclocking – Temperature – Noise
Room temperature at this time is 24 degrees C.
Like the case of R7 265 Dual-X, the only other overclocking software allows the 1050/1500 MHz OC ceiling, separate each TriXX – Sapphire’s software allowed pulled up again. However R9 270 HD 7870 which is to be cut from rename two 6-pin auxiliary power source to one side. Limits on power consumption is evident can foresee. So overclocking capabilities of R9 270 Dual-X high not only to be 1050/1500 MHz, not exploited the full potential of the GPU.
After overclocking performance only increased by 7.5%
Operating temperature of Sapphire R7 265 Dual-X (room temperature 24 degrees C, benchtable):
– Idle: 29 degrees C.
– Gaming (945/1400 MHz Default): 60 degrees C; Fans 39% ~ 2400 rev / min.
– Gaming (@ 1050/1500 MHz): 63 degrees C, 44% ~ 2624 fans rev / min.
R7 270 Dual-X heatsink using the R7 265 general I review in previous posts, so the noise level of this product 1 equivalent. During testing, the radiator works perfectly smoothly. I tried to increase the fan speed, the noise level in one of the speed markers as follows:
– 50% ~ 2970 rev / min: Having a small cry if to listen.
– 60% ~ 3400 rev / min: cry louder, could be heard while using.
– 70% ~ 3770 rev / min: Starting noise, fans cried rushing affect users.
– Beautiful form.
– Performance and p / p good price range.
– Circuit Board tasty, quality components.
– Effective heat dissipation.
– 1 6-pin auxiliary power not to exploit the potential of GPU overclocking.
– Do not nickel-plated heat pipes.
– 2-year warranty.
