amazon Sapphire R7 265 Dual-X reviews
Sapphire R7 265 Dual-X is a good product in every way: form, performance, price, components, heat dissipation.
Contrary to Nvidia, AMD’s R7 and R9 generations are fairly massive. However, despite the full presence of almost all the price range from popular to high-end, Vietnamese users do not seem care with this new series of products. This is due in part to the fact that the product itself is not attractive, and partly due to the madcap hunting of the Bitcoin Virtual Plow. Let’s take a look at some of the AMD models available in the market:
– R7 240: Performance and less p / p than competitor GT 640 and predecessor HD 7730 GDDR5.
– R7 250: Performance and good p / p in the segment, however no breakthrough and only the previous generation is the HD 7750.
– R7 260X: Actually only HD 7790 rename but sold for … higher price.
– R9 270X: Product manufacturers are beautiful design, good performance but p / p is not impressed.
– R9 280, 280X, 290, 290X: Have been hunted by the virtual money hunters.
So at this point, users really need a new breath from AMD blow into the Vietnam market. Sapphire R7 265 Dual-X is such a product. The card is currently priced at $200. This is the segment that users need more choice, no product that satisfies all three aspects of form, performance and cost.
A little extra about Sapphire: This is a super cool brand that turns AMD graphics cards into production. The company always makes users impress and admire the design of the product.
Sapphire R7 265 Dual-X
From the time of AMD’s first generation R7 VGA R9 series, I was stunned by Sapphire’s design. They care for the product from box to VGA. The Sapphire R7 265 Dual-X is no exception. Gamers certainly like this.
The card is carefully packed inside, with a shock-proof plastic bag and a foam case to protect the product.
Sapphire R7 265 Dual-X has a very subtle design. Card length is just enough, not too short to be bad or too long to cause difficulties for the small chassis as well as increased pressure put pressure on the main.
The radiator grille is black. The mask material is made of plastic, but the glimpse is very similar to the metal covered with paint. R7 265 Dual-X is beautifully styled, not bumpy.
The dark brown backdrop of dark brown. Clean water circuit. The components are carefully welded, the quality of the welds are good and they are clean.
Looking at the top and bottom corners, you can see that the radiator is equipped with two large diameter copper heat pipe, which promises good heat dissipation. There are two heat pipes that are not nickel-plated.
The card is not too long so the 6-pin auxiliary power source is set horizontally. I like this kind of horizontal rotation because the plugs are not bad either in the case or on the benchtable. With this 6-pin auxiliary power supply, R7 265 requires the user to have a power supply of at least 400 watts.
CrossFire Bridge supports Dual VGA.
The Sapphire R7 265 Dual-X is equipped with two DVI ports, an HDMI port and a DisplayPort port. With these output ports, users can output three screens simultaneously for both entertainment and work.
It comes with 2 manuals, a driver disc, a DVI-Dsub port and a Molex-6pin transfer cable.
Now go to the part that I like the most: open the radiator detector components. The heat sink is very firmly attached to the circuit board and must be swiveled for a short time before being removed.
It turns out that this is due to some thermal pads. These thermal pads work to increase the contact between the memory chip and the heat sink to cool the memory chips. When removing some removed under heat dissipation, some remain stuck on the chip.
The source phase region for the GPU is equipped with up to four power phases. Each phase is equipped with a large capacitor and a control mosfet.
Surely many will wonder why there is only one mosfet? The Mosfet used for the Sapphire R7 265 Dual-X is not a typical 8 foot type. This DrMos comes with the Fairchild FDMF 6823C, which is capable of controlling up to 50A.
At the right edge of the circuit board, there are two power phases. One phase may supply power to the memory chip, the remaining phase is unclear what function.
8 256 MB of memory is available in 2 GB memory for the R7 265 Dual-X. The memory chip is manufactured by SKhynix, carrying code H5GC2H24BFR.
Excellent heat dissipation with large soles and 2 large diameter copper heat pipes. Heat-treated aluminum foils are cleaned and straightened. The only minus point is that the heat pipes are not nickel-plated with antioxidants, over time will surely get duller.
Sapphire is pretty careful when attaching a screw seal to each of the screw holes to keep the heat sink as rigid as possible without damaging the GPU and motherboard.
While the heat sink and board are relatively good, Sapphire only runs the card at 925/1400 MHz, which is equivalent to AMD’s ref.
TriXX – Sapphire’s OC Toolkit
Sapphire has developed their own pretty OC tool called TriXX. Or that the TriXX allows for extra voltage boost and pulse-to-comfort, while both the MSI AfterBurner and the AMD Overdrive lock the voltage, pulling only the bare 1050 MHz.
The TriXX fully identifies the information of the VGA, BIOS version and driver being used.
OC parameters are simple, intuitive. Users can save overclocking parameters of up to 4 profiles to call at any time. However, the TriXX lacks the Power Limit.
The Fan Control feature allows you to adjust the fan speed according to the temperature levels. With this feature, users can balance between cooling efficiency and noise in all cases.

Overclocking – Temperature – Noise
The moment I performed this test, the room temperature was 26 degrees Celsius.
First mention of TriXX – Sapphire overclocking software makes its products. While MSI AfterBurner and AMD Overdrive only allow up to 1050/1500 pulse, with TriXX, I am not constrained by this. This is extremely useful because the highest clocked R7 265 Dual-X is clocked at 1150/1600 MHz.
At this pulse, performance is up pretty much, up to 22.8%!
Operation temperature of Sapphire R7 265 Dual-X (bench temperature 26 ° C, benchtable):
– Idle: 28 degrees C.
– Gaming (Default 925/1400 MHz): 59 degrees Celsius; Fan 42% ~ 2420 rpm.
– Gaming (@ 1250/1500 MHz): 65 degrees C, fan 43% ~ 2715 rpm.
During the test period, the heatsink worked perfectly smoothly. I try to speed up the fan speed, the noise at some speeds as follows:
– 50% ~ 2970 rpm: There are small cries if you listen.
– 60% ~ 3400 rpm: louder, can be heard while in use.
– 70% ~ 3770 rpm: Noise starts, fan whistling affects the user.

My comments on the Sapphire R7 265 Dual-X just in one word: Good! Good performance, reasonable price, nice appearance, good components, temperature is good – this is all the users find in a graphics card. In terms of p / p alone, the Sapphire R7 265 Dual-X is still a bit lower than the Zotac GTX 660 Synergy is in price range. However, the overall rating (in terms of formality, temperature), the card Sapphire is no less, even marginally better players who are the formidable. In addition, the overclockability of the product is also impressive, up to 20% performance
However, the R7 265 Dual-X is not a complete product and still has 2 minus points. Firstly, the card does not overclock even though the motherboard and components are quite good. Second: warranty period lasts only 2 years.
– Beautiful form.
– Performance and good p / p in the price range.
– Quality components.
– Overclocking well.
– Effective heat sink.
– OC TriXX tool allows high pulse pulse.
– No overclocking compared to the ref of AMD.
– No nickel plated heat pipe.
– Warranty 2 years.
