The total slide deck of AMD'southward next generation Polaris GPU based Radeon RX 480 graphics card has been leaked ahead of launch. Several slides including architectural cake diagrams have been unveiled by Videocardz in an exclusive mail which we will be dissecting downward. The Radeon RX 480 itself will be launching today in just a few hours so expect to see reviews go live in a couple of hours.

The AMD Radeon RX 480 launches in less than 24 hours for a starting price of $199 Usa.

AMD Radeon RX 480 Slide Deck Unveils Polaris 10 Architecture Details - Async Compute, Improved Shaders, Enhanced Geometry Inside RTG's Most Efficient GPU To Appointment

The entire slide deck is full of juicy details regarding the Polaris 10 GPU architecture which will ability the RX 480 and RX 470 graphics cards. While nosotros have already given a technical overlook of these graphics cards, nosotros will now be discussing the Polaris 10 GPU that will be powering the new RX series cards.

AMD Polaris 10 GPU Block Diagram Detailed - 2304 Shaders And A Lot More than

The Polaris ten GPU is based on the 14nm FinFET procedure from Global Foundries. The chip features a single Graphics Command Processor which is allocated 4 ACE (Asynchronous Compute Engines) and 2 Hardware Schedulers (HWS). The consummate Polaris x (XT) flake volition feature 36 compute units where each compute features a full of 64 stream processors. This rounds upward to 2304 stream processors on the flagship Polaris graphics processor.

Each array of ix Compute Units is housed within a shader engine comprising of a single Geometry Engine (4 in total). There are a full of 144 texture units which ways that each CU comprises of 4 TMUs. The Polaris ten GPU also comprises of 32 ROPs and a larger 2 MB L2 cache. There are viii 32-chip memory controllers on the full chip which round up to a 256-bit wide bus interface. Aside from the Graphics cake, the Polaris 10 fleck is also housing the CrossFire, Brandish Port 1.iv-HDR, HDMI 2.0b, video encode/decode dispatch , DMA engine and several other multimedia accelerators.

AMD Radeon RX 480 - Polaris 10 With Enhanced Geometry Engines

AMD has deployed a new engineering science known as Primitive Discard Accelerator which improved the geometry performance through alternative triangles early in the pipeline with zero surface area. The GPU too deploys a new alphabetize cache for geometry with small instances. This helps reduce data movement through the geometry engine so that the GPU can free internal bandwidth resources and maintain higher archaic throughput while geometry is being processed.

The result is a massive increment in geometry performance, peculiarly Tessellation with high amounts of anti-aliasing. With Primitive Discard enabled in Radeon GPUs, the Polaris ten GPU can get up to 3.5x increase in geometry processing such as tessellation.

AMD Radeon RX 480 - Polaris x With Improved Shader Efficiency, FP16 Back up

Polaris also features improved shader efficiency providing better performance per shader core. This is accomplished through using education prefetch which improves efficiency by reducing pipeline stalls and making GPU cache procedure more than efficient, increment per wave instruction buffer size that allows higher single threaded performance along with tuned L2 enshroud.

The Polaris GPUs are likewise capable of native FP16 and Int16 support. This allows FP (Floating Point) performance at half the rate of single precision which is improve tuned for graphics, computer vision and information learning markets. The employ of FP16 results in lower power compared to FP32 compute and besides reduced retention/register usage.

AMD Radeon RX 480 - Polaris 10 With Advanced Asynchronous Compute Capabilities

Asynchronous Compute is 1 of AMD'south strongest feature with GCN based graphics cards and it is back with a lot more advanced features on GCN 4.0. AMD's Async Compute is flexible in the style that it can make graphics and compute work asynchronously.

Polaris can also pre-empt and offer quicker response queue to graphics and compute tasks as needed. The graphics chip selects from the nearly ideal scenario and picks upwardly which resources need to be managed in any of the ways possible. The Polaris 10 GPU houses iv Hardware Schedules defended for Asynchronous compute which will help a lot in DirectX 12 titles supporting the new feature.

AMD Radeon RX 480 - Polaris 10 With Memory / Color Compression

Talking about memory, AMD has updated their Polaris 10 GPU with the latest memory controller that supports the latest 8 GB GDDR5 chips to provide up to 256 GB/south bandwidth along a 256-bit autobus interface. This applied science has been vastly improved over the generations and the Polaris GPU tin compress up to xl% information compared to just 20% on the Fury Ten (Fiji GPU) and 0% on the R9 290X (Hawaii GPU). Color and Delta compression provide a higher peak bandwidth that adds to efficiency.

AMD Radeon RX 480 Graphics Menu Specifications - The Flagship Polaris x GPU With 1266 MHz Core Clock

The Radeon RX 480 volition exist based on the total Polaris 10 GPU which features 2304 unified shaders based on the GCN 4.0 compages. The Radeon RX 480 comes with 144 Texture Mapping Units and 32 ROPs which deliver a texture fill rate of 182.3 GTexel/s and Pixel Fillrate of 40.5 GPixel/southward at a clock speed of 1266.0 MHz. The Radeon RX 480 will be bachelor in reference flavors when it launches tomorrow and will go custom models effectually a week or two later.

AMD Radeon RX 480 Graphics Card:

The RX 480 graphics card volition exist bachelor in two variants, a 4 GB model with a cost of $199 US and a 8 GB model with a price of $229 Usa. The GDDR5 retention on both variants will be clocked at 8 GB/south (2.0 GHz clock), effectively delivering a cumulative bandwidth of 256 GB/s along a 256-flake interface. Based on the 14nm Finfet technology, the graphics card features a 150W TDP and powered by a single 6-Pin connector. Display outputs for the RX 480 include 3 DP 1.3, 1.4-HDR and a single HDMI ii.0b port. This will permit the graphics card to bulldoze resolutions from as low as 1080P (240Hz HDR) to 4K 120Hz SDR / 96Hz HDR or even 5K @60Hz (SDR).
