The XFX R7770 Core Edition ships in an artistic looking box featuring a 3D render of the word ‘CORE'. A nice high resolution image of the product wouldn't go amiss, we think.
A rather disappointing bundle, a ton of literature on the XFX power supply range, fitting instructions and a ‘Do Not Disturb' sign for a door handle.
The XFX R7770 is a tiny little card based around a black PCB. The XFX branded metal cooler is attractive and is finished in a silver and black colour scheme. A single large fan is positioned in the middle. This is a dual slot card.
The R7770 is Crossfire capable in a 2 way configuration. The R7770 has proven popular with users who buy a single card, then add another later for added horsepower.
The R7770 requires power from a single 6 pin connector.
The R7770 is fully loaded, with two DVI ports and a full sized HDMI and DisplayPort connector.
As we know from past experiences, AMD's HD7770 doesn't require a substantial cooler. XFX have opted for a small circular cooler, made from metal and painted black. It resides directly over the core underneath with the remainder of the card cooled actively via the fan.
Above, we can see an overview of the Cape Verde hardware built on the 28nm manufacturing process. The R7770 core is clocked at 1GHZ and the memory @ 1,125mhz (4.5Gbps effective). The HD7770 is bandwidth limited, featuring 1GB of GDDR5 memory connected via a 128 bit memory interface. There are 640 shaders onboard and 16 ROPS/40 TMU's.
Fantastic reading thanks GTX660ti all the way for me !
I have wanted the HD7950 now for quite a while, but cant afford it. ive decided to wait until the next gen, later this year. good article, shows the good GTX660ti performance well.
Im very happy with my HD7870, will do me for some time, and when it doesn’t ill pick one up cheap to CF them,
Now this will totally affect my decision on buying a vga
GTX670 is great, but GTX660 ti is the bargain right now. I like that Sapphire card though, im sick of fan noise 🙁
Good article, very helpful as im thinking of buying one for my new system soon.
Greg, you might want to look at the Asus Direct CUII version of the GTX660Ti – I got one recently to replace a Gainward GTX260GS and the reduction in fan noise is astonishing.
I agree with Andrew. Even though the Gainward GFX cards are very durable, but if you want high quality Nvidia cards that are also silent you should look at the ASUS cards with the Direct CUII cooling solution. It’s really no comparison.
Kitguru said: “Today’s article won’t be featuring the AMD HD7970, HD7990 or Nvidia GTX680 or GTX 690/Titan. Not because we don’t like them, but because very few people can afford to buy them.”
This seems very disingenuous. There’s hardly any difference between the avg. 670 and 7970 prices. Does put nVidia at the top of the charts with the O/C’d 670 though. :
Well its not meant to be disingenuous. the GTX680 is the flagship to battle against the HD7970. If we included the HD7970 then we would need to include the GTX680, sometimes seen for £350.
The point was to try and get a variety of cards and not focus on the flagship single GPU cards.
Bear in mind the GTX670 didn’t get a top award in this test, due to the pricing. The Sapphire HD7950 Vapor X did due to cost, cooling, noise etc.
