It's confirmed the GeForce GTX 760 really is on AMD's crosshair's with the Radeon R9 285. Based on the 28 nm "Tonga" silicon, which is designed to offer "Tahiti" like performance at the energy-efficiency levels comparable to NVIDIA's GK104, the R9 285 features 1,792 Graphics CoreNext stream processors, 112 TMUs, 32 ROPs, and 256-bit wide GDDR5 memory interface, holding 2 GB or 4 GB of memory. The card will feature clock speeds of 918 MHz core, 5.50 GHz memory. AMD claims the R9 285 will be up to 15 percent faster than the GeForce GTX 760. It will start at US $249, with partners coming out with custom-designs on day-one (September 2nd, 2014).

AMD disclosed the first details of its upcoming Radeon R9 285 graphics card, designed to compete with NVIDIA's GeForce GTX 760. Based on the 28 nm "Tonga" silicon, the card features 1,792 of the chip's 2,048 Graphics Core Next 1.1 stream processors, 112 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface. AMD AIBs will have variants with 2 GB and 4 GB of memory. The company didn't disclose clock speeds, but the card will be designed to offer performance rivaling (or outperforming) the R9 280, at energy-efficiency levels rivaling NVIDIA's GK104 silicon. Below are some of the first custom-design graphics cards.

AMD is set to launch its new performance-segment graphics card, the Radeon R9 285, on the 2nd September, 2014. Ahead of its launch, the company is expected to tease the card at its August 23rd press-event, celebrating 30 years of graphics and gaming. On that day, AMD will share "partial" details of the card.

The R9 285 is based on AMD's swanky new 28 nm "Tonga" silicon, which is being drummed up to be AMD's best answer to NVIDIA's GK104. The chip offers performance rivaling "Tahiti," at the power consumption of GK104. The R9 285 is being designed to offer performance roughly that of the Radeon R9 280, at energy-efficiency, and pricing to drop lead on NVIDIA's GeForce GTX 760. A month later, presumably in early October, the company plans to launch the faster R9 285X, offering performance comparable (if not higher than) the R9 280X, at the energy-efficiency levels of GTX 770. "Tonga" physically features 2,048 Graphics CoreNext 1.1 stream processors, 128 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface, which will hold 2 GB or 4 GB of memory.

According to a block diagram of AMD's new 28 nm "Tonga" silicon, it features the same amount of shading power as "Tahiti," if not more. The chip features a total of 2,048 Graphics CoreNext 1.1 stream processors, spread across 32 compute units (CUs). The chip also features 128 TMUs. The block diagram was part of press-material AMD distributed with its recently launched FirePro W7100 professional graphics card, which is based on "Tonga."

The W7100 uses just 28 of the 32 CUs, and hence features 1,792 stream processors. Other features of "Tonga," according to the block diagram, include a 256-bit wide GDDR5 memory interface, 32 ROPs, TrueAudio DSP, and a modern XDMA CrossFire interface. The first consumer graphics card based on this chip is the Radeon R9 285. It is expected to feature 1,792 stream processors, and offer performance rivaling the Radeon HD 7950 Boost at lower power draw, and priced to compete with the GeForce GTX 760. That could leave the possibility of a future "R9 285X" with the chip's full complement of stream processors.

TechPowerUp released the latest version of GPU-Z, the popular PC graphics information, monitoring, and diagnostics utility, which gives you up to date information on your installed graphics processing hardware, and lets you monitor them in real-time. Version 0.7.9 of GPU-Z adds support for several new GPUs, and fixes various outstanding bugs.

To begin with, support is added for new and upcoming GPUs, such as AMD "Tonga," Radeon R9 M275X, FirePro W5100, W9100; NVIDIA GeForce GTX 780 6 GB, GTX 860M, GT 830M, GTX 780M, GT 740, GT 730, GT 720, Quadro NVS 510, FX 380M, GRID K520, and Tesla K40c. Bug fixes include correct release date for Radeon R9 290, more robust NVIDIA PhysX detection, improved fan-speed monitoring on some newer AMD cards, sensor graph overflow/underflow, and fixed French translation.DOWNLOAD: TechPowerUp GPU-Z 0.7.9 | GPU-Z 0.7.9 ASUS ROG Themed

The complete change-log follows.

Here are the first pictures a HIS branded Radeon R9 285, the third in a series of leaked press-shots of cards based on AMD's new performance-segment GPU, designed to take on NVIDIA's bestselling GeForce GTX 760 in not just performance, but also energy-efficiency. The card is based on a new ASIC, codenamed "Tonga," which is rumored to feature a stream processor count identical to one of the variants of "Tahiti," and a 256-bit wide GDDR5 memory interface, holding 2 GB of memory. HIS' card features a compact variant of the company's IceQ X² cooling solution. Its pictures also reveal that the R9 285 "Tonga" will feature XDMA CrossFire, much like the R9 290 series.

Here are the first pictures of the card AMD hopes to take on NVIDIA's bestselling GeForce GTX 760 with, the Radeon R9 285. This particular one, branded by Sapphire, featuring its Dual-X cooling solution. The R9 285 is based on a brand new chip by AMD, codenamed "Tonga." It's rumored to feature the same stream processor count as one of the "Tahiti" variants, while featuring higher clocks, and a narrower 256-bit wide GDDR5 memory interface, a fact confirmed by this card's marketed 2 GB of memory. Given how marketing material of the R9 285 is ready, its launch may not be far away.

In a bid to counter NVIDIA's bestselling GeForce GTX 760, AMD is preparing a new 28 nm GPU, codenamed "Tonga," as detailed in our older article on the chip. At the time of its writing, we had two theories on what "Tonga" could be, one held that it could be a counter to the GM107, and the other, that's is a step above "Curacao," in a bid to counter the GTX 760. We're now learning that AMD could launch the first graphics cards based on this chip, some time in August. The chip will replace the ailing "Tahiti Pro" silicon, from which is carved out the Radeon R9 280. While the R9 280 offers performance competitive to the GTX 760, it loses out big time on power consumption and heat. The cheaper R9 270X, on the other hand, offers lower performance, and similar power levels. "Tonga" could offer nearly as much performance, while featuring a new combination of components, that help AMD lower not just power draw, but also overall costs.

The 28 nm "Tonga" silicon is expected to feature 2,048 GCN2 stream processors, 128 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface. You'll notice that its memory interface is narrower than that of the R9 280, but performance is made up for with a higher stream processor count, and probably higher clock speeds, too. The card could come in memory capacities of 2 GB, with some manufacturers innovating 4 GB variants. There's no word on what the company could end up naming the first cards running this chip.

NVIDIA's energy-efficiency leap achieved on existing 28 nanometer process, using the "Maxwell" based GM107, appears to have rattled AMD. The company is reportedly attempting a super-efficient, 28 nm, mid-range chip of its own, codenamed "Tonga." The chip could power graphics cards that compete with the GeForce GTX 750 Ti and GTX 750. The chip is likely to be based on Graphics CoreNext 2.0 micro-architecture, the same one that drives "Hawaii," which means AMD isn't counting on the micro-architecture for efficiency gains. It could feature an evolution of PowerTune, which works closer to the metal than its existing implementation on "Hawaii." Other features could include Mantle, TrueAudio, and perhaps even XDMA CrossFire (no cables needed). The chip could be wired to up to 2 GB of memory.

Another equally plausible theory doing rounds is that "Tonga" could be a replacement to "Tahiti Pro," designed to compete with the GK104 at much lower power footprint (than "Tahiti"), so AMD could more effectively compete with the GeForce GTX 760. The chip could be similar in feature-set to "Tahiti," with a narrower memory bus (256-bit wide), but higher clock speeds to make up for it. If this theory holds true, then "Tonga" could disrupt both Tahiti Pro and "Curacao XT." Curacao XT (R9 270X) is designed to offer a value-conscious alternative to the $250 GTX 760. The R9 280 is competitive in performance, but takes a beating on the energy-efficiency front, and is also costlier to manufacture, due to the higher transistor count and four additional memory chips. We could hear more at Computex 2014.
