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.

What I'd like to know is why the 7950 is shown in the Idle temp charts and then vanishes from the Load temp charts.Oxford Guy - Wednesday, February 15, 2012 - link
Sorry.. Power consumption charts.I'd like to see the 7950/7970 load power consumption. The idle consumption is less interesting and that's where they're shown.

Me too, the 6850 was worse than the 5850, so I'd expected it to be easily beaten by this generation's 770. Then again, the 6770 was just a 5770, so I suppose I should've learned that the mid-range is barely moving.designerfx - Thursday, February 16, 2012 - link
if you think about the fact of it's price today then it will probably be down substantially in a month - at which point it'd be quite competitive.ce12373 - Wednesday, February 15, 2012 - link
Hmmm. This AMD story sounds like a lot of other AMD stories (cough*cough "BULLDOZER"). Maybe no one has piledriven the point home to AMD yet. Oh well.medi01 - Wednesday, February 15, 2012 - link
Right, and it's a long time that nVidiai stopped producing overpriced "you can fry pancackes with these" GPUs and even hold performance crown? Oh, it's still producing them and AMD still hold performance crown? What a pity.Oh, but AMD went nVidia route with "confuse consumer more" naming scheme? How shameless, do they pay royalties for this to nVidia, the inventor of this rubbish?

AMD has been doing the name bait and switch just as long as Nvidia but since your such a fan boy apparently you haven't noticed. It is obvious from your overheated GPU remarks that you are stuck on some ancient review of a past Nvidia product. And again, AMD has done the same, also in the past, 2900XT anyone?CeriseCogburn - Wednesday, March 21, 2012 - link
The GTX 590 still holds the single card crown.The very strange situation that has occurred is amd holding the single core card crown with 7970, finally passing the 580 after a year or closer to two and I don't remember how long.
This single core crown is gone already gone with the GTX680 benches leaked a few days early.
So amd finally did hold a crown for once in a very long time, for a very short time, 2.5 months or so....with most of that time in very weak or absent stock on retail shelves.

You realize you're kinda the laughing stock of anandtech right? You wait with baited breath for every post remotely including AMD somewhere in the article to give you the opportunity to suck off nvidia and intel. I literally think you might need psychiatric help with that raging superiority complex, then again I've always thought there should be specially designed concentration camps for people like you who never grew out of acting like a blow-hard highschool kid.Oh well, down to business.
Two 7970's (And I mean two 7970's, NOT a 7990) perform better than one Titan, EVERY benchmark has shown it, you can not deny this. And I already know what you're doing to say "BUT THAT'S 2 CARDS VS. 1, NOT FAIR ;[" But see, this is the main point that proves you're a major fucking moron. That.does.not.matter.at.all.
The the Titan is 1000$.
Two 7970's are 800$.
And while yes, it's impressive that a single card can hold it's own against two, it doesn't matter, who is going to spend 200$ more for LESS performance? I'm sure you'll also say "you're just an AMD fanboy." Wrong, I just don't like to waste my money. And I really, really, don't like you.
Nuff said.
Oh and by the way, read it and weep, pussy.
