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.

Bingo. But your numbers look at if you were to want to buy today. You might have bought the 5750 or 5770 at a significantly lower cost during a sale in the past 2.5 years. So individual price comparisons may be different than today's prices.IN ADDITION: the 7770 and 7750 require about 3% less power and produce frame rates about 10% higher than their 57xx counterparts. This is after the 57xx have been out for nearly TWO AND HALF YEARS. I purchased both (the 5750 for one system at $65 and the 5770 for another at $99) about 6 months after introduction. Two years later, there is no compelling reason for me to upgrade. That means AMD is only going to be selling these to new desktop purchasers.... a quickly shrinking market. This cannot be good for AMD.

Since fps is your only metric, itself being a murky and disturbed error filled easily biased mess based upon game set, driver cheating, resolutions, and in game settings chosen, the entire price/perf chart is EPIC FAIL.When your drivers crash, when your game doesn't work, when new games don't work for weeks and months, when dual card drivers are absent, when features like PhysX are no can do - NONE OF IT IS ACCOUNTED FOR....

Obviously all amd has to do is follow the simpleton idiot fps/per dollar formula for all the stuck cursor gsod fanboys to bloviate and screech they saved 20 cents... then the amd forum masters casn continue to lock them out, lock user problem threads, and smart off that "it's works for them on their eyefinity setup theya re starig at right now"...

When a crazed, worship filled, religious zealoutry claims the heavens have opened on the cheap and the devil competition has lost all, beware...
Oh.. wait... sorry talking to the wrong person...

I am curious how high these cards will go before they hit the powertune limits.Ryan Smith - Wednesday, February 15, 2012 - link
I'm still writing up an addendum, but here's what I have for the 7770.Ref 7770: 1125MHz core, 4.8GHz memory
XFX 7770: No meaningful overclock on top of XFX's factory overclock. Crashed at 1160MHz core
As for performance, basically look at the XFX card.

Personally I find that the more interesting cardRyan Smith - Wednesday, February 15, 2012 - link
We didn't do any overclocking tests on the 7750. It was necessary to quickly test it in order to be able to ship it to Ganesh for HTPC testing.DarkSynergyt - Wednesday, February 15, 2012 - link
Might be a stupid question but can the 7750 output audio over HDMI? I'm in the process of building an HTPC and this is the final piece to the build.evilspoons - Wednesday, February 15, 2012 - link
My 6570 can and I'm pretty sure they said in the review that it has all the same features as previous generations for video features.ganeshts - Wednesday, February 15, 2012 - link
Yes, it does. With full bitstreaming options too (even WMA Pro). 7.1 channel LPCM support is also there. No worries. (Of course, hot plugging [ say, moving from a direct monitor connection to an AV receiver input ] causes the audio output to act crazy, but that is the case with every card. Reboot fixes the issue)evilspoons - Wednesday, February 15, 2012 - link
This really drives home how obsolete my GTX 285 is. The 7770 has about equivalent performance and uses *130 watts* less.I need a new video card, but I want to see what Nvidia has for us next - I'm not a fanboy (in spite of all my gaming cards since the 3dfx Voodoo 3 being Nvidia), I'm just genuinely hoping for either some competition to drive prices down or something better to blow us away. Come on guys, get a move on already!
