HTPC Testbed & Software Configuration
Given its position as a sub-75W card, the Radeon HD 7750 has an obvious niche in HTPCs. In order to test out the HTPC capabilities of the 7750, we decided to reuse our existing AMD Llano testbed. 3D is an important aspect, and the AVR / display device have since been updated for this purpose. The table below lists the components in our Llano HTPC testbed.
| AMD Llano HTPC Testbed Setup | |
| Processor | AMD A8-3850 - 2.90GHz, 4MB Cache (1MB/core) |
| Motherboard | ASRock A75Pro4 ATX |
| Disk Drives | OCZ Vertex 2 120 GB (OS) / 1TB Samsung HD103SJ (Media Storage) |
| Memory | G.Skill Ripjaws Series 4GB (2 x 2GB) SDRAM DDR3 1333 (PC3 10666) F3-10666CL7D-4GBRH CAS 7-7-7-21 |
| Video Cards | AMD GDDR5 7750 |
| Optical Drives | ASUS 8X Blu-ray Drive Model BC-08B1ST |
| Case | Antec Skeleton ATX Open Air Case |
| Power Supply | Antec VP-450 450W ATX |
| Operating System | Windows 7 Ultimate x64 |
| Display / AVR | Acer H243H / Pioneer Elite VSX-32 + Sony Bravia KDL46EX720 |
| . | |
Hardware is only one part of the HTPC equation. The various software components used in our testing are tabulated below.
| AMD 7750 HTPC Testbed Software Configuration | |
| Blu-ray Player | CyberLink PowerDVD 12 |
| Standalone Media Player | MPC-HC x86 v1.6.0.4014 |
| Splitter | LAV Splitter (LAV Filters 0.46) |
| Audio Decoder | LAV Audio Decoder (LAV Filters 0.46) |
| Video Decoders | LAV Video Decoder (LAV Filters 0.46) |
| MPC Video Decoder | |
| Renderers | EVR Custom Presenter |
| madVR 0.80 | |
| Notes | LAV Audio Decoder was tested in both decode and passthrough modes |
| LAV Video Decoder was primarily used in the DXVA2 Copy-Back mode | |
| The MPC Video Decoder and EVR-CP renderer were primarily used to ensure that legacy decoding methods were still effective | |
Our first step was to put the 7750 through the HQV benchmarking process.

I thought the 7770 would outperform the 6850 at least. Great review.sigmatau - Wednesday, February 15, 2012 - link
For AMD cards, you look at the second number to indicate performance. An 8 series card like in the 6850 usualy performs as well or slightly better than a next generation 7 series card like the 7770.The 3rd number also indicates performance, but not nearly as much as the second number.

er, not really. A 58xx is faster than a 68xx.sigmatau - Wednesday, February 15, 2012 - link
The 68xx series introduced an anomaly in the formula. But generaly what I stated is true.CeriseCogburn - Saturday, March 10, 2012 - link
The anomaly here is the NVIDIA Gtx460 SMOKES the 7770 on everything, in every test, and costs 33% less.I see the crazed fan base cannot bring themselves to say it.
I'll say it - 19 pages unsaid, over a long time.
THE NVIDIA GTX460 SMOKES THIS CARD RO DEATH, AND THERE'S MORE OF THOSE ON NEWEGG FOR LESS MONEY THAN THE 7770.

My word you are tiresome.nissangtr786 - Thursday, July 5, 2012 - link
Using your logic a gtx 580 smoke the gtx 460.The reason why 7770 costs a bit is because its new technology, power consumption goes down quite a bit. Compare the card to same power consumption of new generation card maybe a 7870 and the 7870 will smoke the gtx 460.
perferformance per watt 7770m smokes the gtx 460.

you seriously need to stop posting. everything you post comes off as rabid nvidia fanatic, because you evidently are one, and you seem to camp outside these benchmarks to say the same thing everytime!! "this thing SMOKES~~~~!! the 7770!!! thats all i look at are the frame rates!!! i dont take anything else into consideration cause im an nvidia superfan"Beararam1 - Thursday, February 16, 2012 - link
Really? I thought the 6870>5850. No?CeriseCogburn - Saturday, March 10, 2012 - link
This 7k series needs some www.verdetrol.com--
LOL - How low can you go amd ?
Seems like more firings and cullings are in the works - or perhaps they already dragged the cat in and are now stuck with perverts.
