Back in the Fray - ATI Radeon HD 4890



Rockin' Threesome - Our Trio of Radeon HD 4890 Cards

ASUS EAH4890

The ASUS EAH4890 is an ideal example of a "vanilla" HD 4890. It sports ATI's reference cooler (which is remarkably similar to the one on the HD 4870), and it comes with standard clock speeds of 850MHz at the core and 3900MHz DDR at the memory. This card should give us a good understanding of the base performance of a HD 4890. As for video connectivity, the card comes with the usual twin DVI outputs and single 7-pin mini-DIN.

It also has the usual bunch of bundled ASUS utilities, but with a little trick up its sleeves. It comes with an updated ASUS SmartDoctor utility, which allows you to manually adjust the voltage of the graphics card. This gives you greater control when attempting to overclock it. These are done at your own risk of course, and we'll be taking a look at it to see how much more overclocking overhead we can achieve.

This is what came with ASUS EAH4890:

  • Driver CD
  • Installation Guide
  • A copy of ASUS GamerOSD utility
  • An ASUS leather mouse pad
  • 1 x DVI to HDMI adapter
  • 1 x DVI to VGA connector
  • 1 x HDTV cable
  • 1 x Molex to 6-pin PCIe power adapter
  • 1 x CrossFire connector


The PowerColor HD 4890

The PowerColor HD 4890 is highly similar to the ASUS EAH4890 as it also comes with a reference cooler and reference clock speeds. Again, like the ASUS EAH4890, it has a 7-pin mini-DIN flanked by two DVI ports.

This is what came with PowerColor HD 4890:

  • Driver CD
  • Installation Guide
  • 1 x DVI to HDMI adapter
  • 1 x DVI to VGA connector
  • 1 x HDTV cable
  • 1 x CrossFire connector


Sapphire HD 4980

Our third and final HD 4890 is the Sapphire HD 4890, which is identical to the other two cards in terms of looks. Don't let looks fool you though, because underneath, it comes factory-overclocked. Memory clock speeds remain unchanged, but core clock speeds have been bumped up to a heady 900MHz - that is 50MHz over a reference HD 4890 and 150MHz more than the HD 4870. It probably still won't outperform a GeForce GTX 285, but should still give us some interesting performance numbers.

Our Sapphire HD 4890 came directly from Sapphire and wasn't in retail packaging. As such, we cannot confirm the packaging, but we do expect it to have the usual assortment of cables and accessories.
