GIGABYTE introduced two new graphics card models over the last week, based on GPUs that have been in existence for a while now. The first is the GV-R645-1GI, a low-profile single-slot graphics card based on the AMD Radeon HD 6450, and the GV-N440-1GI, a cool and quiet full-height double-slot graphics card, based on NVIDIA GeForce GT 440.

The GV-R645-1GI is armed with 1 GB of DDR3 memory over a 64-bit wide memory interface. It features clock speeds of 625 MHz core, with 1100 MHz memory. It uses a tiny, radial-fin fan-heatsink to cool the GPU. Its display outputs include dual-link DVI, HDMI (gold-plated connector), and D-Sub, which is detachable. GIGABYTE tried to pull off a neat marketing trick by mentioning that the card is "PCI-E 3.0 motherboard compatible", something every PCI-Express 2.0 and 1.0 graphics card ever made, already is.

In Japan, Epson does more than selling printing and imaging devices. It sells pre-built PCs. Its latest creation is the Endeavor Pro 750, a gaming PC based on Intel Sandy Bridge-E platform. The Endeavor Pro 750 is housed in an airy aluminum-built case. The case has two permanently-fixed handles on top, and its 3.5/2.5-inch drive bay stack can be access from the front-panel, to give it some hot-plugging capabilities. The front-panel also has two USB 3.0 ports next to audio I/O. It's the insides that are more interesting.

The Endeavor Pro 750 is driven by an Intel Core i7-3930K, though an i7-3960X Extreme Edition processor can be opted for, the CPU is cooled by a custom air-cooler. The processor sits on a custom OEM motherboard labelled Epson, but in all likelihood, it may have been built by any of the major motherboard ODMs, such as Foxconn. There are a variety of memory options, starting from 4 GB, all the way up to 32 GB, with DDR3-1600 MHz being the standard memory type. The base model ships with an AMD Radeon HD 6450 graphics card, but it can be configured all the way up to NVIDIA GeForce GTX 580. Storage options, too, are configurable, with various HDD RAID and SSD (Intel 510 series) available.

Claiming to help owners of 'legacy systems', Hong Kong-based add-in board maker Hightech Information System (HIS) has constructed a Radeon HD 6450 card which is equipped with 2 GB of DDR3 memory and makes use of a PCIe x1 interface.

Suited for compact systems, HIS' new card features a low-profile design, a blue PCB, a passive cooler, 160 Stream Processors, a 64-bit memory interface, GPU and memory clocks of 625 MHz and 1000 MHz, respectively, and three display outputs - D-Sub, dual-link DVI and DisplayPort. No word on pricing.

If all you want this Christmas is an Eyefinity setup but can't afford to invest much in a graphics card then you may be interested in Sapphire's latest creation, the Radeon HD 6450 FleX. This card comes with a sub-60 Euro price tag and is able to power three DVI monitors right out of the box.

Sapphire's HD 6450 FleX takes up two PCI slots, comes with a blue PCB and features a passive cooler, 160 Stream Processors, a GPU clock of 625 MHz, a 64-bit memory interface, 1GB of DDR3 memory set to 1600 MHz, UVD (Unified Video Decoder) 3, and three display outputs, a single-link DVI, a dual-link DVI, and a HDMI 1.4a port (a HDMI to DVI adapter is included in the box).

The Radeon HD 6450 FleX can be found on pre-order priced as low as 54.37 Euro.

Club 3D B.V. releases the new Radeon HD 6450 1GB DD3 Noiseless Edtition, the industry second generation of DirectX 11 capable graphics card.This new card features a heatsink cooler design aimed at the HTPCs users and with UVD3 (Universal Video Decoder), improved tessellation engine and higher clock speeds makes the perfect fit for users who are looking an entry level card that is affordable and packs a punch. Offering a low profile card customers can expect this card to be bundled with 2 Low Profile brackets like usually offered by Club 3D on Low Profile items.

MSI, the leading graphics card and motherboard manufacturer in the world, today announced the release of three new graphics cards based on the AMD Radeon HD6000 architecture: the R6670-MD1GD5, R6570-MD1GD3/LP, and R6450-MD1GD3/LP.

SAPPHIRE Technology has just strengthened its range of graphics cards based on the latest graphics technology from AMD with the introduction of several new models in the HD 6000 series aimed at entry level and mainstream users wanting to benefit from the latest features including multi-screen displays and stereoscopic 3D output.

Several models will be introduced with the latest core graphics technology and offering a choice of memory configurations and outputs. All of them feature second generation DX 11 engines from AMD and on-board hardware video decoding with the AMD UVD (universal Video Decoder) - now in its third generation supporting Blu-Ray 3D for stereoscopic 3D over HDMI 1.4a. In addition, models with DisplayPort output also support Eyefinity multi-screen technology. Eyefinity gives users the ability not only to play games on multiple monitors, but also to work across three or more monitors as though it were one large monitor, bringing huge productivity benefits to applications such as photo editing, music creation and document creation.

When the entry-level Radeon HD 6450 launches this 19th April, it will not be alone. AMD will back it with product launches of both the Radeon HD 6570 and Radeon HD 6670, according to fresh reports. With it, AMD will have completed its Radeon HD 6000 series product launches, in almost all price-points, top to bottom. Incidentally, the three were also launched together as OEM-only products back in February.

Based on the 40 nm Caicos silicon, HD 6450 packs 160 stream processors, and a 64-bit wide GDDR5/GDDR3 memory interface, designed for low-profile, single-slot graphics cards. The HD 6570 and HD 6670, on the other hand, are both based on the 40 nm Turks GPU, both feature 480 stream processors and 128-bit wide GDDR5 interface. The two are differentiated with the HD 6570 having lower clock speeds.

AMD apparently unveiled its new entry-level GPU, the Radeon HD 6450 today, with some leading sites publishing mini performance reviews (check out Today's Reviews on the front page). The new GPU is intended to be an integrated graphics substitute, which gives desktops all the essential features that today's desktop environments demand, such as DirectX 11 support, Aero acceleration, various kinds of HD video hardware acceleration features, apart from the obvious benefit of discrete GPUs: not taxing the system memory as frame buffer.

The HD 6450 is based on the 40 nm Caicos GPU, it packs twice the amount of shader compute power as the previous generation, packing 160 VLIW5 stream processors, 8 TMUs, 4 ROPs, and a transistor count of 370 million. The 160 stream processors, with a core speed of 625~750 MHz (differs between AIBs), churn out compute power of up to 240 GFLOPs. It packs a 64-bit wide memory interface, that supports GDDR5 (clocks: 3.20 GHz to 3.60 GHz) and GDDR3 (1066 MHz to 1600 MHz). It has an idle board power of 9W, and max board power of 27W. Most implementations are low-profile single-slot, some even passive. The reference board features display outputs that include DVI, HDMI 1.4a, and D-Sub. Expect a $50~$60 price point. The official announcement however, is slated for April 19, or at least that's what we were told.Image Courtesy: TechReport

AMD released the entire entry-mid portion of the Radeon HD 6000 series overnight, for OEMs only. The cards won't be available to consumers (retail) as yet, but does give away specifications of two new GPUs that AMD is carving these SKUs out of, Turks and Caicos. Built on the 40 nm process, Turks packs 480 VLIW5 stream processors, is DirectX 11 compliant, and sports a 128-bit wide GDDR5 memory controller that supports GDDR3 on lower SKUs. Radeon HD 6670 and HD 6570 are based on Turks. Both have all 480 stream processors enabled, differ in memory type/amount and clock speeds. The HD 6670 carries clock speeds of 800 MHz core, 1000 MHz (4.00 GHz GDDR5 effective) memory, and is available with memory amounts of 512 MB or 1 GB. The 128-bit wide memory interface churns out bandwidth of 64 GB/s.

The HD 6570 is also based on Turks, but features clock speeds of 650 MHz core, and two different memory clock speed specifications based on the memory type opted for by the manufacturers. If a manufacturer chooses GDDR3, it's clocked at 900 MHz (1.80 GHz GDDR3 effective), with a memory bandwidth of 28.8 GB/s. If it's GDDR5, it's clocked at 1000 MHz (4.00 GHz effective), 64 GB/s bandwidth. Up to 2 GB of memory can be opted for GDDR3 designs, while up to 1 GB can be opted for GDDR5-based ones. While the HD 6670 reference board uses a full-height design with a single-slot fan-heatsink, HD 6570 is designed for low-profile cards, best suited for HTPCs or SFF PCs.
