Temperature
Our biggest grouse with the Radeon HD 4850 is its high temperatures. With a 55nm core, we had expected something like the level of a Radeon HD 3870 X2 perhaps. Instead, we got one of the highest temperatures we have seen on a GPU for a while, with the core exceeding 80 degrees Celsius constantly under load. Even idle temperatures were not much better, only dipping slightly below 80. The single slot fan’s rather sedate spin could be a reason and you can expect vendors to be attaching all sorts of custom coolers to tame this warm beast. If you’re worried about heat and less concerned about noise, turning up the fan speed manually is the best we can recommend for a standard Radeon HD 4850.
Power Consumption
ATI’s PowerPlay implementation on the Radeon HD 4850 was a bit disappointing. NVIDIA looks to have done a better job scaling down the power consumption of its mammoth GTX 200 GPUs at idle, though of course at load, the Radeon HD 4850 was among the lowest in our comparison, roughly equal to the GeForce 9800 GTX. Given that the typical GPU should spend much of the time idling, ATI needs to do more work here (which is exactly what ATI is doing at the moment the last we discussed of this issue with them). A CrossFireX setup also should consume a fair amount of power so be prepared for that if you’re looking to get a relatively affordable pair of Radeon HD 4850 cards.

* Information not available.
- Power consumption data (watts) is measured from the wall power source and includes all power supply and system losses. Additional correction isn’t needed.
- CPU Max is defined as running a compute-intensive test application that maximizes processor usage and therefore power consumption.
- These numbers reflect a 23°C (73.4°F) ambient running environment. Increased ambient temperatures require faster fan speeds which increases power consumption. At 35°C (95°F), 50W should be added to reflect increased power consumption.

Radeon HD 4850 X2 video card [in 1 benchmark]
ATI
Radeon HD 4850 X2
- PCIe 2.0 x16 interface
- Core clock 625 MHz
- Video memory size 512 MB
- Memory type GDDR3
- Memory frequency 1990 MHz
- Maximum resolution
Description
ATI started Radeon HD 4850 X2 sales on November 7, 2008 at a suggested price of $420. This is a desktop video card based on the TeraScale architecture and 55 nm manufacturing process, primarily designed for office use. It has 512 MB of GDDR3 memory at a frequency of 1.99 GHz, and coupled with a 256-bit interface, this creates a throughput of 63.68 Gb / s.
In terms of compatibility, this is a two-slot PCIe 2.0 x16 card. The length of the reference version is 267 mm. The connection requires one 6-pin cable and one 8-pin cable, and the power consumption is 250W.
It provides poor performance in tests and games at the level of
2.88%
from the leader, which is NVIDIA GeForce RTX 4090.
