HD 4670 Crossfire Outperforms HD 4850

Pre-release 3DMark tests show that two Radeon HD 4670 graphics cards in Crossfire multi-GPU mode outperforms a single Radeon HD 4850 card. The HD 4670 cards score just a little above the HD 4850 in three tests that include 3DMark06 in Shader Model 2.0 mode, the same benchmark in SM 3.0 mode and 3DMark Vantage.

The cards scored 54xx 3DMarks in SM2.0 and 65xx 3DMarks in SM3.0 tests, a 4850 on the same test-bed produced 49xx and 57xx respectively. With 3DMark Vantage, the Crossfire setup churned out 7300, with the single HD 4850 just 100 points behind at 7200. These scores can be attributed to the raw texturing power the HD 4670 cards have despite memory bandwidth advantage staying with the single HD 4850. Indications are that the HD 4650 won't scale as well since (at least reference models) lack hardware Crossfire.

Gigabyte Silent Radeon HD 4850 in the Works

Gigabyte might well be the first AIB partner for ATI to release the first passively cooled Radeon HD 4850 accelerator, and a 1 GB one at that. The Gigabyte GV-R485MC-1GH sports the RV770 graphics processor clocked at 625 MHz and 1 GB of GDDR3 memory clocked at 1.00 GHz. Gigabyte is to use its "Multi-Core" passive cooler that consists of two arrays of aluminum fins, with two copper heatpipes each conveying heat from the core to the fin arrays. The card will feature Ultra Durable 2 high-grade electrical circuitry with what vaguely looks like a 4 + 2 phase power design. The GV-R485MC-1GH will be available soon. Word is that PowerColor would follow Gigabyte with their passively cooled Radeon HD 4850 model.

HIS has finally brought out its IceQ 4 series HD 4800 series graphics accelerator, this one uses the ATI Radeon HD 4850 graphics processor and uses the fourth generation IceQ 4 dual-chamber cooling technology and continues to maintain a premium look and feel while offering higher levels of cooling performance and the usual UV-sensitive cooler. The card uses reference ATI GPU and memory clock speeds. Expreview reports that this card is already listed by Japanese sales partner Akihabara and priced at US $ 210 there.

HIS has two more models added to the IceQ 4 series: Radeon HD 4850 IceQ 4 Turbo (H485QT512P) comes with the core clocked at 650 MHz with 2.00 GHz and 512 MB of GDDR3 memory. Also on offer is a 1 GB variant (H485QS1GP). It uses reference ATI clock speeds. For more details, please visit the HIS IceQ series micro-site here.

Passive PowerColor HD 4850 Pictured

The guys over at have got hold of a photo showing a passively cooled PowerColor Radeon HD 4850.
The card...utilizes 54 aluminium fins, an all-copper base and four heatpipes to help keep it cool. The high-rise design, however, rules out users with low-profile HTPC chassis.
Considering the temperatures the actively cooled HD 4850 reaches, I cannot imagine a passive cooler is wise. However, this cooler is considerably larger than the reference cooler and it will be interesting to see how it performs, if and when it is released.
