Primarily based on the brand new RDNA 3 structure, AMD Radeon RX 7000 sequence video playing cards have a number of vital enhancements, together with a swap to silicon chiplets, a brand new ray tracing engine, new synthetic intelligence accelerators, AVI encoding capabilities, and high-bandwidth connectivity. The flagship GPU of the 7000 sequence is the AMD Radeon RX 7900 XTX. It isn’t constructed to interrupt the financial institution, because the designers’ purpose was reportedly to create one of the best graphics card beneath $1,000. $1,000 is roughly INR 97,500 after taxes, so AMD definitely has the value proper, at least formally. It stays to be seen if that is actually one of the best graphics card at this value and if the retail costs keep inside the official value vary.
AMD Radeon RX 7900 XTX specs
Shifting from a monolithic design to a chiplet design includes a number of trade-offs, primarily with the connections that assist the completely different chiplets talk with one another. AMD claims it makes use of an ultra-fast connection that delivers as much as 5.3 TB/s for the chiplets to assist with this. Talking of chips, now we have a Graphics Computing Chip (GCD) that’s constructed on TSMC’s 5nm course of, and 6 Reminiscence Cache Dies (MCDs) bundled for the GPU. Mainly, there’s a graphics processor within the middle, surrounded by very quick reminiscence, positioned proper on the bundle. Additionally, there may be at all times DRAM after the reminiscence cache. The capabilities of every MCD are divided into AMD Infinity Cache operate and interplay with DRAM chips.
AMD makes use of 24 GB of GDDR6 chips, which along with the cache reminiscence by way of a 384-bit bus present a bandwidth of as much as 3500 GB/s. The AMD Radeon RX 6950 XT primarily based on RDNA 2 had a throughput of 1793.5 GB/s, however the bus was a lot narrower. And the NVIDIA RTX 3090 with GDDR6X chips on a 384-bit bus reached 936.2 GB/s.
Returning to the GPU core, now we have 96 compute items (CUs), leading to 6144 stream processors. That is 64 stream processors per CU. RDNA 2 had the identical density of stream processors per compute unit. So the place did all the additional transistors go? RDNA 3 has a brand new compute factor for AI acceleration, and there are 192 AI accelerators, that is 2 per CU. As for Ray Accelerators (RA), RDNA 3 nonetheless has 1 RA per CU.
The structure enhancements enabled a number of new options, which we are going to discuss later.
AMD Radeon RX 7900 XTX performance
Testing a brand new graphics card proper at the middle of our Zero1 Awards testing was no simple activity. We’ve not had time to replace lots of our benchmarks for older GPUs, so we have restricted the record of examined GPUs to only some lately examined graphics playing cards. This is the setup we used for our evaluate:
TEST SETUP
Processor – AMD Ryzen 9 7950X
CPU cooler – Corsair H115i RGB PLATINUM
Motherboard – ASUS ROG CROSSHAIR X670E HERO
RAM – 2x 16 GB Kingston Renegade FURY 6000 MT/s
SSD – WD Black SN850X 2 TB NVMe SSD
Energy provide unit – Cooler Grasp MWE 850 V2 Gold
Time Spy is a DirectX 12 primarily based artificial check that offers you an excellent approximation of the standard of your graphics card. We will see that the RX 7900 XT manages to get a big performance increase over the RX 6950 XT, however falls shy of the graphics behemoth RTX 4090.
Port Royale in one other check from UL Benchmarks, which supplies a good suggestion of the ray tracing performance of graphics playing cards. The performance scaling right here appears fairly linear, provided that the raytracing cores have solely elevated barely.
A shock discovery is that the brand new AMD RDNA 3 playing cards lastly work effectively in all APIs. OpenGL was a powerful level for years till the swap to RDNA passed off, and with RDNA 3 Workforce Pink managed to regain the lead.
Gaming performance in HITMAN 3 seems excellent. It is definitely higher than the RX 6950XT at all resolutions examined, but it surely falls wanting the RTX 4090.
Gaming performance in Witcher 3 can be fairly just like what we noticed in HITMAN 3, besides the sting is not as large.
Shadow of the Tomb Raider truly confirmed a barely increased FPS than the RTX 4090 at 1080p, which was fairly stunning. All the pieces else appears to scale appropriately.
One other stunning indicator was the load temperature. You’d count on flagship GPUs to be pushed fairly onerous, however the triple fan unit on the RX 7900 XTX does a very good job contemplating it isn’t an enormous card.
AMD Radeon RX 7900 XTX Value and Availability
AMD Radeon RX 7900 XTX and 7900 XT can be accessible on the market from December 13, 2022. The Radeon RX 7900 XTX is priced at INR 98,000 and the RX 7900 XT is priced at INR 90,000 in India. These costs embrace tax and are indicative costs shared by AMD. Whether or not retailers will keep on with these costs stays to be seen within the coming days.
Verdict
AMD Radeon RX 7900 XTX was not designed to compete with the likes of NVIDIA RTX 4090. That is simple to see from the performance figures in addition to the value of the playing cards. One is nearly twice as costly as the opposite. With that stated, the AMD Radeon RX 7900 XTX reveals a noticeable performance enchancment over earlier era AMD graphics playing cards and is definitely aggressive in its class. Contemplating how AMD is knocking FSR out of the park, the Radeon RX 7900 XTX would make an excellent 4K gaming graphics card, and it even appears moderately priced. As well as, this card will match most pc circumstances.
