Having cropped up at retail yesterday, AMD's yet-to-be-announced Radeon HD 4890 has now been revealed by a selection of images at Asian website coolaler.com.
The forthcoming GPU - expected by many to arrive in April - is shown below with the dual-slot cooler that's found on many existing Radeon HD 4870s.
Flip it over, and there's little change to the PCB, too. The card sports dual-DVI and TV-out connectors, requires two six-pin PCIe power connectors, and features eight GDDR5 memory chips.
What has changed are frequencies. Running Catalyst Control Center, the card's GPU shows a frequency of 850MHz and its 1GB of GDDR5 memory is clocked at an effective 3,900MHz. That's a healthy bump from the 750MHz GPU and 3,600MHz memory found on a stock-clocked Radeon HD 4870, but whether or not the card can topple the world's fastest single GPU solution - NVIDIA's GeForce GTX 285 - remains to be seen.
As always, we'll await AMD's official release, and we'll then be on hand to bring you our in-depth analysis.
