Product Showcase
So, pictures then, below you can see the Radeon HD 7750 and 7770 Ghz edition, these are 1GB model cards. Included with all cards will be manual and a demo and driver CD, power converters and monitor connector converters to get your multi-monitor freak on.

As usual we see a nice dark/red looking card with what you may expect from AMD. The 1.5 Billion transistor encounting 28nm Cape Verde based core is tied to a whopping 1GB memory -- which is a lot for entry level products.
The reference 7770 cards are clocked at a 1000 MHz core frequency and the GDDR5 memory runs at 4.5 Gbps (effective data rate as GDDR5 has a quad data-rate, so effectively that quadruples that number) the memory bus is 128-bit though. The 7750 cards are clocked at 800 MHz btw.
Here we can see the backsides, the cards will fit pretty much any chassis, with the 7750 actually being a single slot solution. The backside of the PCB shows a very non-complex design, that's typically a very good sign.

Connectivity wise the output connectors will vary per brand. But on the reference 7770 card we see four connectors supporting all high-resolution monitors. We get two display port connectors (mini), HDMI and a DVI connector. The 7750, due to its single slot design, gets a DP, HDMI and a DVI connector.

The reference R7770 has a power consumption of roughly 80 Watts whereas the R7750 consumes roughly 55 Watts under your typical gaming load. The boards' overall power consumption from idle to load is excellent really. Expect an idle wattage of roughly 10 Watts and, when the monitor goes into power save mode, the card throttles down even lower towards 3 Watts.

You will need to hook the 7770 up to your power supply with a 6-pin PCIe PEG connector. We recommend a 500 power supply to start with, with one card of course.
We review the AMD Radeon HD 7850 and 7870. These two new mid-range cards are going to shift the dynamics in the graphics arena alright, as the entire package including performance is really impressive for the 7800 series. A product series that is to replace the 6800-series performance-wise, it is based on AMD's 28nm process and of course the latest Graphics Core Next GPU architecture.
AMD Radeon HD 7750 and 7770 review
It's now February 2012 and AMD thinks they have a new '5770' in their hands. The codename is 'Cape Verde' for the GPU, and the graphics cards deriving from them are the Radeon HD 7750 and 7770 One GHz edition. This is not a refresh it is a completely new GPU based on the same technology that powers the R7900 series, the GCN architecture. Head on over to the next page where we'll meet and greet Cape Verde, aka Radeon HD series 7700.
AMD Radeon HD 7970 review
We review the Radeon HD 7970. Injected in the 499 EUR / 549 USD price tag bracket the product will have to compete directly with the equally expensive GeForce GTX 580, it will actually be a decent notch better then that IMHO. The results that you'll witness today will not dishearten. Where it matters (the latest and newer games) the Radeon HD 7970 will be a good 20%, 30% sometimes even 40% faster then the competition, and in the world of enthusiast graphics performance that's what we call, a product with a little extra booty.
