In addition to the passive cooling system, which fans will appreciate the quiet, 3D-card can boast twice the memory – 1 GB GDDR5. A month before the exhibition was seen development Gigabyte, plans to equip the Radeon HD 4770 in such a large amount of memory attributed to the company XFX.

Fee for the  passive cooling is that the cooler claim to two slots. Cooler construction  consists of three massive heat pipes and ribbed radiator, which is the length extends beyond the boundaries of the printed circuit board. To connect the monitors serve as connectors D-Sub, DVI and HDMI.

Data on the frequencies at which the components of GV-R477SL-1GI, yet, and no information about price and timing of the emergence of new items for sale.

According to the source, based on the same GPU RV790, and that the Radeon HD 4890 Atomic, has issued another card – Radeon HD 4890 Vapor-X. As shown by name, it is equipped with cooling Vapor-X. 

Circuit board Radeon HD 4890 Vapor-X is blue. It has 1 GB of memory GDDR5, related to the GPU 256-bit bus. 

As seen in the pictures, payment is equipped with connectors D-Sub, DVI, HDMI and DisplayPort. The components of the accelerator operating at full frequencies – 850 MHz (GPU) and 3900 MHz (memory). Home sales Radeon HD 4890 Vapor-X is expected in the coming weeks.

New received the designation in the catalog Gigabyte GV-R465D2-1GI. It has a GPU with 320 stream processors, 128-bit memory bus, 1 GB GDDR2, large cooler, connectors D-Sub, DVI (HDMI via adapter). Site is designed for installation in the AGP slot 8h. It supports technology DirectX 10.1, OpenGL 2.1, and CrossFireX. Clock frequency components manufacturer does not specify, so that it can be assumed that they have equal values for staffing – 600 MHz for GPU and 800 MHz for memory. Approximate price of the product is 100 dollars.

New designated HD4890 PCS + +. She had inherited from his predecessor as the HD4890 PCS +, all the key features, including the cooling ZEROtherm. According to the manufacturer, ZEROtherm provides a good balance between efficiency and noise level. 

A distinctive feature of PowerColor HD4890 PCS + + is the work of the components at higher frequencies. By default GPU core frequency is 1010 MHz and memory frequency – 1100 MHz. To ensure stable operation at such frequencies and create a reserve for «disperse», designers HD4890 PCS + + improved nutrition and the use of its better parts. In particular, it is a polymer capacitors and MOSFET power transistors with low resistance value of the channel open. 

The accelerator will be available as a separate product and as part of the set, released a limited series, which includes a full version of the game Battle Forge.

Sapphire company not long to wait, and said an official press release release 3D-card Radeon HD 4890 Atomic. However, for our regular readers a message Sapphire did not come as a surprise – the first evidence that Sapphire is preparing a debut «atomic» version of 3D-ukoritelya Radeon HD 4890, were published in late April. 

New products Sapphire has become one of the first accelerators, core GPU which runs at 1 GHz. At this point, it is the fastest graphics solution uniprocessor in the world. The accelerator is aimed at enthusiasts and will be released a limited series. It cools home cooler, which uses technology evaporator chamber Vapor-X. 

GPU core clock speed is 1 GHz, clock speed 1 GB of memory GDDR5 – 1050 MHz. The kit, packaged in the recognizable briefcase, in addition to the card, the cable is HDMI. 

In the coming weeks, the company promises to release a few more options Radeon HD 4890.

Gainward Radeon HD 4850 GS GLH

Site has been named Radeon HD 4850 Golden Sample Goes Like Hell (Radeon HD 4850 GS GLH). Its specifications include 512 MB of memory GDDR5, 256-bit memory bus, 2-slot cooler, connectors D-Sub, DVI, DisplayPort and HDMI. 

GPU clock speed and memory would be 700 and 3600 MHz respectively. Approximately, Gainward Radeon HD 4850 GS GLH appear on the market in the coming weeks.

The pictures show the 3D-card-based GPU RV790. 

GPU clocked at 850 MHz, which is 100 MHz higher than the Radeon HD 4870. 

On board is 1 GB of memory GDDR5, calculated at the frequency 3900 MHz (in case of Radeon HD 4870 – 3600 MHz). The memory is connected to a 256-bit bus. Site supports DirectX 10.1 and CrossFireX. 

Reference model has the usual layout, and took two seats. The color of the printed circuit board – red. 

Site is equipped with two connectors DVI. The date of withdrawal Radeon HD 4890 is considered the beginning of next month.

The new accelerator of that company has received GC-HD4670XTG4-E3 codename, and also has the GDDR4 memory type (instead GDDR3/DDR3) and higher working frequencies. They comprise 750 and 2200 MHz for the chip and memory respectively. 
At the core of the product – 55-nm nucleus RV730XT with 320 stream processors, its complement of 512 MB memory with 128-bit access. In contrast to the development of Sapphire, GeCube cards have no HDMI output, and D-Sub, it is equipped with a pair of DVI connectors and an HDTV-Out.

Sapphire HD 4650

As a user of such a card of 512 MB of DDR2 memory with a 128-bit access, 600 MHz core frequency, memory – 800 MHz. Supported maximum resolution 2560 x 1600 (Dual-link DVI) or 1080p (HDMI), the size of the map – 173 x 69 x 22 mm. 

Sapphire HD 4650

The card has received the product code 11140-18-20R (VD3243), and is already sold in Japan at a price of ~ U.S. $ 85
