AMD Unveils The Radeon R9 285 "Tonga Pro" Graphics Card - 190W TDP, DirectX 12 Support and Priced At $249 US

AMD has officially unveiled their next generation "Tonga" graphics processing unit which will be featured inside the Radeon R9 285 series graphics cards. The Tonga graphics bit has been unveiled at AMD's ongoing "30 Years of Graphics and Gaming Commemoration" event where the chip maker has appear several new technologies including the Radeon R9 285 graphics card.

AMD Unveils The Power Efficient Radeon R9 285 "Tonga Pro" Graphics Menu

This isn't the first time nosotros are hearing of Tonga equally it has already been launched with the FirePro W7100 GPU for professional person marketplace back at SIGGRAPH 2022. The Tonga GPU is highly efficient and the bones purpose of the new cards is to rival the upcoming Maxwell generation of graphics processing units from NVIDIA. As noted, the offset generation Maxwell architecture featured on the GM107 was just the beginning delivering the most low power and highly efficient chip in the industry. NVIDIA is on the verge of introducing their next generation GM204 core which will be integrated on their performance segment cards unveiling in September 2022. AMD has to answer them sooner or later and at present is the best fourth dimension to innovate new products which volition replace the year old rebrands featured in the Radeon R9 and R7 series lineups. AMD also has a separate result planned in September related to a new loftier-terminate bit but we volition talk about it later on.

The Radeon R9 285 is built on the Tonga Pro compages but before going into the architectural details, allow's focus on the details of the card itself. The Radeon R9 285 has 1792 stream processors, 112 TMUs and 32 ROPs. The Radeon R9 285 will ship with two GB of GDDR5 retentivity running across a 256-bit interface. The core clock is maintained at 933 MHz and boost clock at 988 MHz while the memory frequency is maintained at 1375 MHz which results in a 5.5 GHz constructive retentivity clock pumping out 176.2 GB/due south bandwidth. The card additionally comes with XDMA CrossFire technology and TrueAudio DSPs which allows to switch load off the CPU and put sound processing task to the DSPs instead for enhanced manageability and functioning.

Although the reference variants ship with 2 GB GDDR5 memory, at launch we will see a couple of manufacturers launch 4 GB GDDR5 variants too along with factory overclocked variants which arrive on second September 2022. The Radeon R9 285 specifications might exist similar to Tahiti simply the thing that makes it so diverse is actually the core itself which has been optimized and re-engineered to evangelize more operation at lesser wattage. The card requires a 2 vi-Pin power connectors with a TDP of 190W and evangelize performance on par with the Radeon R9 280X graphics carte du jour which is astonishing. Brandish outputs include Dual-Link DVI, HDMI and a full length display port. AMD has been silent most the price just from what nosotros can encounter, the card will come to retail at $249 United states of america followed by its bigger brother, the Radeon R9 285X for $299 Us arriving in late September. With the Radeon R9 285 details done, permit'southward move on to the architectural assay.

AMD Tonga GPU Architecture and Block Diagram:

From the cake diagram previously posted, we got to know that the Tonga GPU houses eight ACE (Asynchronous Compute Units) compared to just two on Tahiti and each shader engine has its own geometry processor and a rasterizer unit of measurement which houses eight Compute Units per block. The Tonga Pro variant has 2 of these CUs disabled resulting in 1792 stream processors. The Multimedia accelerators block has been updated with the XDMA CrossFire engine and addition of TrueAudio DSPs which deliver the TrueAudio tech. Last we can run across a large L2 cache, role of which is blacked out which points that this model doesn't feature the full core but it does have a larger cache compared to Tahiti which may tell why the card is less resilient to bandwidth.

The Radeon R9 285X which is the Tonga XT variant features the total 32 CU die which includes 2048 stream processors, 32 ROPs and 128 TMUs. We don't accept any specifics regarding the clock speeds, fifty-fifty the ones reported for the Radeon R9 285 are based off manufactory overclocked variants so we can't be and then sure merely 918 MHz is what's existence said the reference clock for Radeon R9 285 then nosotros can look something effectually 933 MHz+ for the Tonga XT variant. What's weird is that the Radeon R9 285X is allegedly featuring a 384-scrap memory omnibus compared to 256-bit bus on its Pro variant and besides includes a higher VRAM updated from 2 GB to three GB.

The Radeon R9 285 is already considered a mid-tier board from its looks and blueprint merely the Radeon R9 285X could be a decent update over Radeon R9 280X' Being like to Tahiti in lath blueprint just the updated core with new architecture will leverage the performance and while the Tahiti XT variants have a TDP of 250W, we can see a sub 200W TDP for Tonga XT variants which arrive in September as reported past the source. The pricing for the Radeon R9 285 volition autumn in between $250 United states while the Radeon R9 285X could retail at $300 U.s.a. since Tahiti XT and Tahiti Pro based cards have already received major toll cuts during the last few months. Do note that the specifications for the Tonga Pro and the 32 CU full die for Tonga XT are more or less confirmed.

AMD Radeon R9 285 Firestrike Functioning Numbers:

The 3DMark Firestrike Performance numbers for the Radeon R9 285 were also revealed inside the Footnotes displayed at the stop of the live event. The performance numbers for 3DMark Firestrike for the Radeon R9 285 were noted equally 7066 in Operation and 3513 in Extreme compared to 5650 and 2774 marks respectively for the GeForce GTX 660.

AMD Never Settle Space Packet Promotion:

Aside from all the announcements, AMD also introduced their latest Never Settle: Infinite Edition parcel which includes several AAA titles set in the infinite and some outside information technology. The main attractions of the bundle are Star Citizen, Space Run III, Conflicting Isolation and Habitat. AMD Never Settle Space
