HQV Benchmark 2.0 is an updated version of the original tool and it consists of various video clips and test patterns which are designed to evalute motion correction, de-interlacing, decoding, noise reduction, detail enhancement and film cadence detection.
There are two versions of the program, standard definition on DVD and high definition on Bluray. As our audience will be concentrating on HD content so will we.
This has a total of 39 video tests which is increased from 23 in the original and the scoring is also up from a total of 130 to 210. As hardware and software gets more complicated, the software has been tuned to make sure we can thoroughly maximise our analysis.

A score of 196 points is class leading right now, the ideal solution for high definition media playback on a big screen.
Good card, but I cant help but feel this range of cards from AMD is rather dull and lifeless. why remove alot of the shaders on the cards? makes no sense to go back a step. negates the gains from the manufacturing process and increasing the clock speeds
Very dull launch day, they need to drop the prices.
Sapphire always do good coolers, but id love to know who in AMD thought it was a good idea to lose 140 stream processors on the new card? the HD6770 had 800 !
Crossfire performance is really good. id like to see results from two of the OC’d models.
great cooler, but the card undeneath hasn’t hit the spot im afraid.
I can’t see anybody in the UK listing a Sapphire SKU with 1150Mhz Core clock…
see Scan/Dabs have a 1120 listed…
Hi Muppett, you aren’t the first person to ask me about this, and ive contacted Sapphire today and they told me that SCAN have the core clock speed listed at the older speeds. It should be 1150mhz. you will hopefully see this change on SCAN Shortly.
Thanks for letting us know.

This card works best underclocked if you have a clocked version, some of the overclocked 7770’s have an odd issue that causes your screen to flicker. Performance wise its a good mid/entry range card but a complete failure from the 6000 series. One thing does stand out about the 7000 series though, their using better cooling which would be a nice addage if only the prices would drop.
@Frank I would guess it has to do with the dye shrinkage from 40nm scale to 28nm, I would have settled for a thousand stream processors if it meant abandoning such a useless shrinkage. My guess they shrunk the dye in order to control heat and leverage power out put. Which is just piss poor marketing strategy if you ask me.
