PowerColor's Radeon HD 5670: DirectX 11 Goodness Under $100
George Ross, June 15, 2010


ATI's latest surge in the PC gaming market has not been built on having the absolute fastest video cards available but giving the customer a video card that has good performance at decent price points. This has helped the value conscious PC gamers out there to see their games play with higher resolutions and quality settings. Now that DirectX 11 has been out for awhile now ATI has solidified its position in the PC gaming market by offering a complete top to bottom lineup of DirectX 11 supporting video cards. The subject of today's review is closer to the bottom of the pile, but can it offer the kind of performance you are looking for and still be priced under $100?

Packaging and Contents

PowerColor has done a decent job with the packaging of their HD 5670. The card is kept from moving to much during shipping by some bent up cardboard.

All you get with this card is a driver CD and an generic quick install guide that reminds you to plug in your video cards external power cord even though this particular video card doesn't have an external power plug.

The Card

This card has a pretty large aluminum heatsink and fan combo that makes it take up two slots. This card also has CrossFire connectors and this is something that not all HD 5670's possess. As far as connectors go you get D-Sub, DVI, and HDMI on the card with no included adapters. I would have rather seen a DVI to D-Sub adapter and DisplayPort connector on the card instead of the D-Sub.


This particular HD 5670 is a good overclocker it managed to get a 65Mhz boost in core frequency and a 40Mhz boost in the memory frequency. This 8% increase in core clock speed and 4% increase in memory speed resulted in a 6% increase in overall average frames per second across all game tests as you will see below.

Test Hardware
It is unlikely you will see an HD 5670 paired with a LGA 1366 based setup out in the wild, but this pairing does give you an idea of how this card can perform under the some of the best conditions. The overclocked 8800GT is clocked the same as a 9800 GTX+ so it should offer similar performance. Here are the rest of the particulars on the hardware that was used in testing.

Gaming Benchmarks

You may have noticed that the 8800GT OC didn't complete its Crysis runs at the high and very high settings at 1900x1200 resolution with 8xAA. This has never happened before with this card and even after much tweaking I could not get that card to run those two tests. Every other test ran without any problems.

The HD 5670 may not be the fastest video card out there but if the games you are playing are not as taxing on a system as let's say Crysis or S.T.A.L.K.E.R. Call of Pripyat. Then the HD 5670 offers solid performance at lower resolutions and depending on the game at higher resolutions as well.

The DirectX 11 Performance Hit

As you can see DirectX 11 doesn't make that big of a difference in S.T.A.L.K.E.R. call of Pripyat, but when you look at a synthetic benchmark like Unigine's Heaven benchmark there is a clear differnce.

GPU Temperature
All tests were done with an ambient temperature of 26 degrees Celsius in an open case environment. Considering the how hot the test environment was these are some pretty good numbers.

Power Consumption
As expected the power consumption of this card is lower than that of the other cards that were used in testing. The HD 5670 must represent the top of the PCI express power limits as its power isn't that far off from the rest of the pack and those all require external power.

For a purchase price that is around $90 PowerColor's HD 5670 offers DirectX 11 gaming although not at the highest quality settings and resolutions. This is not a problem for a lot of people out there who spend a good bit of time playing older games or games that don't require much horsepower like World of Warcraft. So for those people who are looking to build a budget oriented gaming rig or looking to replace a DirectX 9 series video card on the cheap PowerColor's HD 5670 is definitely worth a look.
