AMD "Tonga" GPU Arrives This August

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.

Arctic Announces Four New Universal Graphics Card Coolers

Arctic Cooling announced four new graphics card coolers, the Accelero Hybrid II-120, the Accelero Xtreme IV, the Accelero Xtreme IV 280, and the Accelero Twin Turbo III, pictured below in that order. The Accelero Hybrid II-120, as its name might suggest, is a combination of an air and liquid cooling solution. It combines a large heatsink that cools memory and VRM; and a closed-loop GPU cooler, with a 120 mm radiator assembly. The cooler supports all modern graphics cards, including those based on NVIDIA's GK110 (eg: GTX 780 Ti), GK104 (eg: GTX 760), GK106 (eg: GTX 660); and AMD's "Hawaii" (eg: R9 290X), "Tahiti" (eg: R9 280X), and "Pitcairn/Curacao" (eg: R9 270X). Arctic is pricing this cooler at $130.

Moving on, there's the Accelero Xtreme IV. It features a similar backside heatsink to the Accelero Hybrid II-120, which cools the memory and VRM; while the GPU is cooled by a large aluminium fin-stack heatsink. The heatsink confines to two expansion slots, but is taller than a standard full-height add-on card. The heatsink is 288 mm long, 104 mm tall, and 54 mm thick. It features two aluminium fin stacks arranged along the length of the heatsink, to which heat drawn from the GPU is conveyed by five 6 mm-thick copper heat pipes. The heatsink is ventilated by three 92 mm fans that each have 4-pin PWM control. The Accelero Xtreme IV supports all the GPUs that the Accelero Hybrid II-120 does. It's priced at $100.

AMD Announces the Radeon R7 265 Graphics Card

AMD launched the Radeon R7 265, a mainstream graphics card designed to fill the price gap between the $139 Radeon R7 260X, and the $179 Radeon R9 270. Based on the 28 nm "Curacao" silicon, the card features a core configuration not too different from that of the previous generation Radeon HD 7850. On offer are 1024 stream processors, 64 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface, holding 2 GB of memory. The card supports DirectX 11.2, OpenGL 4.3, and Mantle. With it, AMD hopes to take on $150-ish NVIDIA GeForce products such as the GTX 650 Ti Boost, and probably the upcoming GTX 750. It starts at US $149.99.

AMD Readies Radeon R7 265

In a bid to ward off the GeForce GTX 750 threat, AMD is working on a new Radeon R7 series GPU, the R7 265. The SKU, interestingly, isn't based on the "Bonaire" silicon as the R7 260X, and is instead based on a cut down "Curacao" silicon, the same chip on which the R9 270 and R9 270X are based. While the R9 270 series chips share a common core configuration with 1,280 stream processors each, the R7 265 will feature one that's similar to that of the Radeon HD 7850 from the previous generation, which means 1,024 stream processors, 64 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface. Its core clock speed is expected to be around 900 MHz, and memory at 4.80 GHz (GDDR5-effective), which works out to a memory bandwidth of 153.6 GB/s. AMD could target the US $149 to $159 price range with the Radeon R7 265.

Radeon R9 270X a Faster Radeon HD 7870 "Tahiti LE"

AMD's performance-segment Radeon R9 270X could prove to be a winning sub-$200 product for the company. Sources affiliated with a leading online retailer revealed that the SKU could greatly resemble the limited edition Radeon HD 7870 "Tahiti LE," possibly with higher clock speeds and stream processor count. "Tahiti LE" is a major variation of "Tahiti," which features not just lower numbers of stream processors and TMUs, but also a narrower 256-bit wide GDDR5 memory interface. The die is mated with a more compact BGA package that has lower pin count, thanks to the narrower memory interface, and probably fewer power/ancillary connections. Sources reveal the R9 270X to be "a crippled HD 7950," which could indicate a stream processor count of 1792, higher than the 1536 of Radeon HD 7870 "Tahiti LE." The TMU count could be proportionately higher due to the way they're structured on the GPU; at 112, compared to 96 on "Tahiti LE." The clock speeds are still under the wraps. AMD set an SEP price of the Radeon R9 270X at $199.

Radeon R9 and Radeon R7 Graphics Cards Pictured Some More

Here's a quick recap of AMD's updated product stack, spread between the R9 and R7 series. This article can help you understand the new nomenclature. AMD's lineup begins with the Radeon R7 250 and Radeon R7 260X. The two are based on the 28 nm "Curacao" silicon, which is a variation of the "Pitcairn" silicon the previous-generation Radeon HD 7870 was based on. The R7 250 is expected to be priced around US $89, with 1 GB of RAM, and performance rated at over 2,000 points by 3DMark Firestrike benchmark. The R7 260X, features double the memory at 2 GB, higher clock speeds, possibly more number crunching resources, Firestrike score of over 3,700 points, and a pricing that's around $139. This card should turn up the heat against the likes of GeForce GTX 650 Ti Boost.

Moving on, there's the $199 Radeon R9 270X. Based on a chip not much unlike "Tahiti LE," it features 2 GB of memory, and 3DMark Firestrike score of over 5,500 points. Then there's the Radeon R9 280X. This card, priced attractively at $299, is practically a rebrand of the Radeon HD 7970 GHz Edition with. It features 3 GB of RAM, and over 6,800 points on 3DMark Firestrike. Then there are the R9 290 and R9 290X. AMD flew dozens of scribes thousands of miles over to Hawaii, and left them without an official announcement on the specifications of the two. From what AMD told us, the two feature 4 GB of memory, over 5,000 TFLOP/s compute power, and over 300 GB/s memory bandwidth. The cards we mentioned are pictured in that order below.



More pictures follow.

Radeon R7 260X Pictured, Too

In addition to the Radeon R9 290X pictured earlier today, AMD will also be unveiling the Radeon R7 260X upper mid-range graphics card. Pictures of the card were leaked to the web. At the moment, we have no clue as to what chip the card is based on, but we're hearing two codenames, "Curacao" and "Bonaire XTX." "Curacao," in our best guess, is a variant of "Pitcairn." "Bonaire XTX" could be a higher-performing variant of the "Bonaire" silicon AMD launched the Radeon HD 7790 with. Given the way components are arranged behind the GPU, we're inclined to believe the card pictured below is based on "Curacao." Gotta give AMD marks for trying out something different with the cooler shroud design.

Radeon HD 9000 Series Arrives This October: Report

When AMD re-branded most of its Radeon HD 7000 series SKUs to HD 8000 series, for OEMs, we saw this coming from a parsec away. AMD's next discrete GPU family for the retail channel will be placed along the Radeon HD 9000 series, and it debuts no later than this October, according to a Guru3D report. Interestingly, the report states that the first parts in the family will be based on existing 28 nanometer silicon fab processes, and will be codenamed "Curacao" and "Hainan."

We've had our run-ins with "Curacao," from time to time. It's been rumored to be an upgrade of existing "Tahiti" silicon, with 2,304 stream processors based on Graphics CoreNext 2.0 architecture, 144 TMUs, 48 ROPs, and a 384-bit wide GDDR5 memory interface. The Guru3D report adds to that with the mention of an improved front-end, which adds four asynchronous computing engines (ACEs), and three independent geometry engines.
