Our first look at AMD’s “Turks” GPUs comes in the form of Sapphire’s Radeon HD 6670. Unlike with the 6800s, the 6670 lines up nicely with the Radeon HD 5670 and will replace the older card once its stock runs out. The newer card also provides a nice spec boost to persuade you to make it your next upgrade.
The Radeon HD 6670 features six SIMDs for a total of 480 stream processors, 24 texture units, and eight ROPs. The memory controller runs on a 128-bit bus, and the model Sapphire sent us was equipped with 1GB GDDR5, which will help when pumping out frames at medium and high resolutions. The core and memory clocks are set to the stock 800MHz and 1,000MHz, respectively.
This card also bests the last generation by supporting AMD’s UVD3, better texture iltering, a more tessellation-friendly architecture, Blu-ray 3D-compliant HDMI 1.4a, and DisplayPort 1.2. Not every 6670 will necessarily come with a DisplayPort output, but thankfully, Sapphire included one on the backplane. here are also DVI and HDMI ports here. The lack of a CrossFire connector effectively rules out Eyefinity-resolution gaming in anything more stressful than Left 4 Dead 2. This card also requires no additional power connectors to run.
Sapphire’s 6670 is dual-slot, just like the reference cards we got from AMD, but full-height (unlike the reference card). Although disappointing for HTPC users, this card’s other ideal users generally have plenty of room around the PCI-E x16 slot. Sapphire made a bigger card to handle a more substantial cooler, which made the card notably quieter than the stock model.
In the benchmarks, the card per-formed admirably given the fact that we tested with some punishing AA and AF settings. You will see better performance at higher resolutions with those features turned of. Overall, the Sapphire Radeon HD 6670 is an affordable option for casual gamers who play at or below 1,920 x 1,080 or HTPC users who want to beef up their rig without blowing their budget.
