AMD has unveiled the all-new Radeon RX 7900 XT and Radeon RX 7900 XTX, their latest high-end GPUs based on the all-new RDNA 3 architecture and manufactured using a number of scalable ‘chiplets’ designed to be processed using a 5nm process. built on. Both will be available worldwide from 13 December. While the flagship Radeon RX 7900 XTX is priced at $999 (approximately Rs. 81,875 before taxes), the Radeon RX 7900 XT, which is a step down, costs $899 (approximately Rs. 73,680). Suggested retail prices for India have not been announced yet. AMD claims 70 percent better performance than the previous generation, or 54 percent more performance per watt, based on the RDNA 2 architecture.
Competing with Nvidia’s GeForce RTX 4000 series, the new Radeon RTX 7900 XTX packs 96 compute units, clock speeds of up to 2.3GHz, and 24GB of GDDR6 RAM. Total board power consumption is rated at 355W. The slightly more affordable Radeon RX 7900 XT has 84 CUs, 2GHz clock speed, and 20GB of GDDR6 RAM. The power consumption for this model is 300W. AMD’s Promotional images show two standard 8-pin PCIe power connectors for both models, as well as DisplayPort, HDMI, and USB Type-C video outputs. Partner brands will be able to customize their offerings.
Both Radeon RX 7000 series models have so far announced support for the DisplayPort 2.1 standard for 4K output at 165Hz to 4K at 480Hz. There is also hardware-level support for 8K 60fps AV1 encoding, as well as simultaneous encode/decode with the AVC and HEVC codecs.
Classic monolithic GPUs are divided into graphics compute dies (GCDs), which consist of the compute units that make up the graphics rendering pipeline, as well as several memory cache dies (MCDs). The Radeon RX 7900 XTX will have six MCDs, each on a 64-bit wide bus, amounting to 384 bits, while the Radeon RX 7900 XT has five active MCDs that equate to a 320-bit bus. While GCDs are manufactured on a 5nm node, MCDs use a 6nm process, allowing AMD to mix and match components to optimize manufacturing resources and cost.
AMD claims that ray tracing is 50 percent faster than Previous Generation Thanks to new AI instructions and better throughput. Compute units can now issue double instructions, new AI accelerators have been added to each CU, and different stages of the graphics pipeline can now run at different clock speeds. More details about performance, including competitive position against Nvidia’s GeForce RTX 4000-Series Offerings And this new intel arc gpuWill likely be announced at that time.
The company sees a 2.7X improvement in bandwidth for its next-gen Infinity Cache implementation thanks to better algorithms than the previous generation. The company also says that it is stuck with GDDR6 RAM in the interest of power efficiency.
