AMD trying to jump ahead of nvidia
This week AMD showcased their brand new architecture for their upcoming, unannounced line of GPUs that are expected to be launching in the first half of this year. AMD have stated that their highest end GPU sporting this architecture can easily out perform nvidia’s gtx 1080 and the titan x and based on what we’ve seen this is very believable.
AMD said at CES this week that the new Vega architecture is designed to remove many traditional constraints from gaming, VR, professional design and machine intelligence arenas. this new technology vastly upgrades the GPU memory architecture as well as turbo-charging the geometry pipeline and introducing a new compute and pixel engines.
what AMD state as the four most important parts of the Vega architecture are “the worlds most advanced geometry architecture, next generation geometry pipeline, next generation compute engine and an advanced pixel engine”.
Their official line about these four parts are as seen below.
The world’s most advanced GPU memory architecture: The Vega architecture enables a new memory hierarchy for GPUs. This radical new approach comes in the form of a new high-bandwidth cache and its controller. The cache features leading-edge HBM2 technology which is capable of transferring terabytes of data every second, doubling the bandwidth-per-pin over the previous generation HBM technology. HBM2 also enables much greater capacity at less than half the footprint of GDDR5 memory. Vega architecture is optimized for streaming very large datasets and can work with a variety of memory types with up to 512TB of virtual address space.
Next-generation geometry pipeline: Today’s games and professional applications make use of incredibly complex geometry enabled by the extraordinary increase in the resolutions of data acquisition devices. The hundreds of millions of polygons in any given frame have meshes so dense that there are often many polygons being rendered per pixel. Vega’s next-generation geometry pipeline enables the programmer to extract incredible efficiency in processing this complex geometry, while also delivering more than 200% of the throughput-per-clock over previous Radeon architectures.1 It also features improved load-balancing with an intelligent workload distributor to deliver consistent performance.
Next-generation compute engine: At the core of the Vega architecture is a new, next-generation compute engine built on flexible compute units that can natively process 8-bit, 16-bit, 32-bit or 64-bit operations in each clock cycle.2 These compute units are optimized to attain significantly higher frequencies than previous generations and their support of variable datatypes makes the architecturehighly versatile across workloads.
Advanced pixel engine: The new Vega pixel engine employs a Draw Stream Binning Rasterizer, designed to improve performance and power efficiency. It allows for “fetch once, shade once” of pixels through the use of a smart on-chip bin cache and early culling of pixels invisible in a final scene. Vega’s pixel engine is now a client of the onboard L2 cache, enabling considerable overhead reduction for graphics workloads which perform frequent read-after-write operations.
To better put all of this tech and numbers into perspective, AMD released a video showing off Vega in action, playing Doom on Ultra settings at 4K while maintaining a frame rate of 60+FPS. with doom being one of the most graphically intensive games available on the market at the moment this is a very impressive achievement.
AMD have been catching up with nvidia for a while now with their GPUs just a little further ahead than their CPUs maybe this is finally the year that AMD can overtake nvidia and really light a fire underneath them to make the gtx 1100 series the best ever seen otherwise they could really be in trouble from the rapidly rising AMD.
