HIS Radeon HD 7750 iCooler review

You've been hearing about several codenames and that can be a little confusing. It's simple really, in the market we have entry level, mainstream and high-end products. When you notice 'Cape Verde' that's the entry level Radeon HD 7700 series of graphics cards. 'Pitcairn' will be the codename the mainstream products will hide (R7800) under, and finally 'Tahiti' is the codename for the most high-end products.
- Entry level = Cape Verde = Radeon HD 7700 series
- Mainstream level = Pitcairn = Radeon HD 7800 series
- High-end level = Tahiti = Radeon HD 7900 series
The entire segment from top to bottom will be released in Q1 2012. The 7900 series has been launched, now it's time for entry-level, the Radeon HD 7700 series.
It is important to understand that there are significant changes in this family of GPUs. The GPU architecture was overhauled, AMD moved towards a 28nm process technology, the new cards are all PCIe gen 3 compatible and there have been significant changes on power consumption. We'll address all the features separately of course.
With the launch of the Radeon HD 7000 series Eyefinity has been updated to version 2.0. DDM audio is now fully supported (you hear audio on the actual monitor it's played on), a new 5x1 landscape mode is introduced, and you may now create custom multi-monitor resolutions.
Radeon HD series 7700
We start off with the GPU overview (architecture we'll discuss later). AMD now bakes GPUs on the all new 28nm node, in very simple wording that means they can put more transistors on a smaller area.
The Cape Verde core has a good 1.5 Billion transistors, the internal architecture has changed, we'll talk a little deeper about that in a minute. But as a result:
- The Radeon HD 7750 is packed with 512 shader processors harbored in Compute Unit segments (8 of them).
- The Radeon HD 7770 is packed with 640 shader processors harbored in Compute Unit segments (10 of them).
Memory wise both cards will pack 1 gigabyte of DDR5 memory, quite a bit for entry level products. The memory bus is 128-bit, but combined with the gDDR5 memory (which is quad data rate) you do get a decent chunk of much needed memory bandwidth, which the GPU certainly can use. The memory clock will be 1125 MHz, being quad data-rate (gDDR5) that results in an effective data rate of 4500 MHz or 4.5 GHz. This will give the Cape Verde GPUs 72 GB/sec of framebuffer bandwidth to do its thing in.
The Cape Verde GPU packs 1.5 billion transistors, but if you can't apply a fast enough clock frequency it would become a problem. Well, that's not an issue for AMD either, the R7750 is clocked at 800 MHz while the Radeon HD 7770 will get a reference core clock frequency at a full GHz.
We test and review the a HIS Radeon HD 7950 HIS IceQ X, this 30 CM sized beast is one heck of a graphics card. Custom PCB, custom cooling, it's low noise and being a Boost edition card series, it clocks in at 950 MHz.
HIS Radeon HD 7850 4GB iPower IceQ Turbo review
We test and review the a HIS Radeon HD 7850 iPower IceQ Turbo as single card and in Crossfire today. The HIS Radeon HD 7850 iPower IceQ Turbo is a factory overclocked 4GB version of the Radeon HD 7850 graphics card.
HIS Radeon HD 7970 X Turbo edition review
We review the HIS Radeon HD 7970 X Turbo edition. With this card they took the new Tahiti XT2 and redesigned the R7970 board from ground up. though very long the end result is a 31cm PCB with mane power phases and optimizations. Fun to see are the voltage and FAN monitor LED options. Most impressive however is the sheer amount of monitor connectors HIS injected into this product, four DisplayPort connectors, one HDMI and a DVI connector. If needed you can go for Eyefinity6. Oh did I mention already that the factory set boost clock frequency is 1180 Mhz ?
HIS Radeon HD 7950 ICEQ Turbo review
We review the HIS Radeon HD 7950 IceQX Turbo. The product comes factory overclocked very nicely for you as it is running a gentle 900 MHz clock frequency. HIS uses a custom PCB and dual-slot cooler making the card very easy to install. Despite that factory overclock and that cooler the noise levels remain at very low levels whereas the GPU temperatures remain downright excellent as we'll show you in this review.
