XFX Radeon RX 480 Double Dissipation Pictured

Here are some of the first detailed pictures of XFX Radeon RX 480 Double Dissipation graphics card. The card combines a custom-design PCB with a meaty custom cooling solution by the company, to support factory-overclocked speeds and overclocking headroom further still. The cooling solution, from which the card derives its name, features two aluminium fin-stacks, to which heat drawn from a copper base is conveyed by four 6 mm-thick copper heat pipes, and ventilated by a pair of 90 mm spinners.

These fans can be detached from the cooler without needing any tools, and without even having to detach the cooler shroud. A back-plate finishes off the cooling solution. The PCB draws power from a single 8-pin PCIe power connector, and uses a 6-phase VRM with high-end International Rectifier DirectFETs to condition it for the GPU. The card features factory-overclocked speeds in excess of 1300 MHz. The card features 8 GB of memory. Display outputs include a DVI connector, besides three DisplayPort 1.4 and one HDMI 2.0b. XFX could launch the card later this week.

Radeon R9 295X2 Press Deck Leaked

Here are some of the key slides from AMD's press-deck (presentation) for reviewers, for the Radeon R9 295X2 dual-GPU graphics card, ahead of its April 8 launch. The slides confirm specifications that surfaced earlier this week, which describe the card as bearing the codename "Vesuvius," having two 28 nm "Hawaii" GPUs, and all 2,816 stream processors on the chips being enabled, next to 176 TMUs, 64 ROPs, and 512-bit wide GDDR5 memory interfaces. Two such chips are wired to a PLX PEX8747 PCI-Express 3.0 x48 bridge chip. There's a total of 8 GB of memory on board, 4 GB per GPU. Lastly, clock speeds are revealed. The GPUs are clocked as high as 1018 MHz, and memory at 5.00 GHz (GDDR5-effective). The total memory bandwidth of the card is hence 640 GB/s.

The Radeon R9 295X2 indeed looks like the card which was pictured earlier this week, by members of the ChipHell tech community. It features an air+liquid hybrid cooling solution, much like the ROG ARES II by ASUS. The cooling solution is co-developed by AMD and Asetek. It features a couple of pump-blocks cooling the GPUs, which are plumbed with a common coolant channel running through a single 120 mm radiator+reservoir unit. A 120 mm fan is included. A centrally located fan on the card ventilates heatsinks that cool the VRM, memory, and the PCIe bridge chip.

PowerColor Radeon R9 290X PCS+ Unveiled

PowerColor may have been the first AMD add-in board vendor to launch a custom-design Radeon R9 290X graphics card with its R9 290X LCS, which is basically an AMD reference PCB with a factory-fitted EKWB FC-R9-290X water-block; but its air-cooled non-reference cards have been nowhere in sight, until now. PowerColor posted these pictures of the Radeon R9 290X PCS+, its premium factory-overclocked and air-cooled graphics card based on AMD's flagship GPU. The company's Radeon R9 290 (non-X) PCS+ is expected to look identical.

Pictures reveal the card's PCB to be largely based on AMD's reference design, perhaps with variations on the choice of components. PowerColor has a knack of splurging on expensive, high-quality components on its PCBs (think International Rectifier and Coilworks VRM components, Samsung and SK Hynix memory chips, etc.), and we expect a similar treatment for the R9 290X PCS+. The two-slot cooling solution featured on this card is making its debut with it. It features a network of aluminium fin stacks to which heat is fed by copper heat pipes, and which are ventilated by a trio of 80 mm fans. PowerColor didn't reveal clock speeds, launch date, or pricing.

Gigabyte G1.Assassin 3 Motherboard Detailed

Gigabyte showed off an early version of its upcoming high-end socket LGA2011 motherboard, the G1.Assassin 3, at IDF. Based on the same Intel X79 Express chipset as its predecessor, this board is built in the standard ATX form-factor. It draws power from a combination of 24-pin ATX and 8-pin EPS connectors. It uses a 9-phase VRM to condition power to the CPU socket, which uses PowIRstage driver-MOSFETs by International Rectifier. The CPU socket is wired to eight DDR3 DIMM slots, supporting up to 64 GB of memory, and four PCI-Express 3.0 x16 slots. A couple of PCI-Express 2.0 x1 slots complete the expansion area.

Storage connectivity on the G1.Assassin 3 includes four each of SATA 6 Gb/s and SATA 3 Gb/s ports. Network connectivity includes two gigabit Ethernet interfaces, from which one is driven by an Intel-made controller, and an add-on card with 802.11ac WLAN, and Bluetooth 4.0. A hyped up feature here is its Creative Sound Core3D audio, with a high SNR DAC, audiophile-grade OPAMP circuitry with user-replaceable amps (Gigabyte calls this AMP-UP). Six USB 3.0 ports, and a number of USB 2.0/1.1 ports make for the rest of it. Gigabyte didn't finalize heatsink designs for the VRM or PCH, and there's no word on when exactly the company plans to launch the thing.

MSI GeForce GTX 780 Lightning Pictured

Ahead of its launch, pictures of MSI's GeForce GTX 780 Lightning graphics cards were leaked to the web by HardwareZone (now redacted), and reposted by WCCFTech. Pictures reveal never before seen PCB and cooler designs. To begin with, MSI is using a brand new cooling solution called TriFrozr. It combines a large compound dual fin-stack heatsink, to which heat is fed by seven 8 mm-thick heat pipes, with an array of three fans, two larger 100 mm ones on the edges, and a smaller 70 mm one in the center. The fans feature independent control system, which lets you tweak speeds of individual fans, over software. An LED-lit badge doubles up as a GPU load indicator. A swanky back-plate lines the reverse side.

Under this elaborate cooling solution is a brute of a PCB. Drawing power from a pair of 8-pin PCIe power connectors, the custom-design PCB by MSI features a 20-phase digital PWM voltage regulation, which use a combination of high current chokes, International Rectifier PowIRstage, DirectFET chips, tantalum capacitors, and MSI's GPU Reactor module that cuts out electrical noise. The GPU is wired to 7 GT/s rated Elpida-branded memory chips, and three (that's right, three) GPU BIOS ROMs. One stores a failsafe reference BIOS, another factory-OC air BIOS, and one that primes the GPU for liquid-nitrogen cooling-assisted overclocking. MSI is expected to launch the GTX 780 Lightning on August 28, 2013, priced around $800.

ZOTAC GeForce GTX 770 Extreme Edition Detailed

ZOTAC launched its premium GeForce GTX 770 Extreme Edition SKU in the Greater China region. The SKU outranks AMP!, and offers a suite of enthusiast features, such as a strong VRM, and better air cooling. It's not unlike the GTX 680 Extreme Edition or GTX 670 Extreme Edition. To begin with, the GTX 770 Extreme Edition features a slightly updated Gamer Force cooler, with higher aluminum fin density for the GPU heatsink, and a chunkier metal heatsink to cool the VRM. A back-plate cools components on the reverse side of the PCB.

The GTX 770 Extreme Edition features the same exact PCB as its predecessor, featuring a 12-phase (8+3+1) VRM, which makes use of noise-free chokes, a combination of conductive polymer and tantalum capacitors, three proadlizers (multi-phase capacitors for power conditioning), and International Rectifier PowIRstage driver-MOSFETs. A combination of CHiL CHL8318 (8-phase) and CHL 8214-03 (4-phase) chips are used to run the VRM. The main heatsink uses a copper base (not vapor-chamber) to make contact with the GPU, from which five 8 mm-thick nickel-plated copper heat pipes sprout out, transporting heat to the far-reaches of the heatsink. A pair of 92 mm PWM-controlled fans ventilate the heatsink, which are held by a sporty aluminum shroud.

GIGABYTE Also Shows off F2A85XN-WiFi Feature-rich Mini-ITX Motherboard

In addition to the G1.Sniper A85X, GIGABYTE also showed off what could go on to become an HTPC builder favorite, the F2A85XN-WiFi mini-ITX motherboard. The board draws power from conventional 24-pin ATX + 4-pin ATX connectors, and uses a 6-phase VRM to power the APU. Built with the Ultra Durable 4 Plus construction, the board uses high-grade PowIRstage driver-MOSFETs and VRM controllers, made by International Rectifier. The FM2 socket is wired to two DDR3 DIMM slots, supporting up to 32 GB of dual-channel DDR3-2133 MHz memory, and a PCI-Express 2.0 x16 slot. On the connectivity front, the F2A85XN-WiFi offers four SATA 6 Gb/s ports, four USB 3.0 ports, dual-link DVI and two HDMI display outputs, 8-channel HD audio, gigabit Ethernet, 802.11 b/g/n WiFi, Bluetooth 4.0, and a number of USB 2.0/1.1 ports.

GIGABYTE G1.Sniper 5 and G1.Sniper M5 Motherboards Pictured

At a media event held in its Taipei headquarters, GIGABYTE demonstrated its AMP-UP integrated audio solution that will feature on some of its upcoming motherboards. On that pretense, it even got to show of two of its top socket LGA1150 motherboards, built for Core "Haswell" processors, the G1.Sniper 5, and the G1.Sniper M5. Positioned in gamer-overclocker targeted G1.Killer series, the two boards are based on Intel Z87 Express chipset. The G1.Sniper 5 is the larger standard ATX motherboard; while the M5 is a compact micro-ATX offering. The pictures also confirm that socket LGA1150 retention module and bolt-spacing is identical to sockets LGA1155 and LGA1156.

The G1.Sniper 5 appears to feature a 16-phase VRM, which uses ferrite-core chokes, and the same International Rectifier PowIRstage components as Ultra Durable 5 motherboards from the previous generation. This time around, the CPU plays a greater role in voltage regulation. The driver-MOSFETs on the board are cooled by an active fan-heatsink, which also has a liquid channel running through it, so you could make it part of your CPU loop. Thankfully GIGABYTE didn't let its imagination run away with designs of the other heatsinks on the board, one of which cools the Z87 Express chipset, and the other we imagine, a PLX PEX8747 48-lane PCI-Express 3.0 bridge chip. This chip gets you 4-way SLI/CrossFireX support.

GIGABYTE Shows Off G-Power Accessory for GeForce GTX TITAN

With NVIDIA clamping restrictions on graphics card makers' ability to make custom design PCBs for its flagship GeForce GTX TITAN GPU, the likes of GIGABYTE are opting for the next best thing - creating accessories that enthusiasts can mod their GTX TITAN graphics cards with, at the cost of product warranties. A little earlier this month, the company unveiled its WindForce 450W VGA cooler, which is capable of handling GTX TITAN. At a more recent event, it showed of G-Power, a supplementary voltage regulation module, which is similar in principle to EVGA EPower and ASUS Matrix PWM.

The device is a small PCB with high-capacity power leads on one-end, which need to be soldered on to the reference GeForce GTX TITAN PCB, and a combination of 24-pin ATX and 8-pin EPS connectors on the other. Between them is a 6+1 phase VRM, with components that appear similar to the ones used on GIGABYTE Ultra Durable 5 motherboards, consisting of 60A ferrite core chokes, International Rectifier PowIRstage IR3550 driver-MOSFETs, and International Rectifier IR3563A controller. The G-Power module stabilizes power on the GTX TITAN PCB, preventing voltage droop from breaking the overclock. There's no word on how GIGABYTE plans to sell these.

ZOTAC Gives GeForce GTX 670 Extreme Edition Treatment

ZOTAC seems to have a 2-pronged approach to the GeForce GTX 670, depending on the region it's being sold in. While it took advantage of the compact reference PCB by NVIDIA to come up with the space-saving GTX 670 TwinCooler (ZTGTX670-2GD5TCR001), it did the exact with the GTX 670 Extreme Edition. The card is based on the same exact design as the GTX 680 Extreme Edition, down to its lavish voltage regulation circuitry, with just the GTX 670 ASIC taking the place of the GTX 680.

The card ships with out of the box clock speeds of 1111 MHz (GPU base), 1202 MHz (GPU Boost), and 1652 MHz (memory actual), or 6.60 GHz (memory effective). It draws power from 6-pin and 8-pin PCIe power connectors, and conditions power using a 13-phase VRM that consists of noise-free chokes and PowIRstage DrMOS chips by International Rectifier. Power is further conditioned by a trio of multi-phase FPCAPs, and tantalum capacitors. Like the GTX 680 Extreme Edition, the card features the entire overclocker-friendly feature-set, including OC+ Module, dual-BIOS with LN2-friendly BIOS, voltage measurement points, temperature and phase loading LEDs.
