AMD’s next-gen Radeon RX 7900 XTX and XT launch December 13 for $999 and $899

a brand-new opposition appears–

RDNA 3 GPUs will utilize lots of chiplets to counter Nvidia’s massive RTX 4000 series.

AMD is getting ready to introduce its next-generation Radeon RX 7000- series GPUs next month, and today the business shared more information about the cards’ rates, efficiency levels, and the brand-new RDNA 3 GPU architecture that will power all of its graphics cards for the next number of years.

The launch starts at the high-end, with the Radeon RX 7900 XTX and RX 7900 XT. AMD will introduce both of these GPUs on December 13, with the 7900 XTX beginning at $999 and the XT beginning at $899(cards made by AMD’s partners will certainly press these costs up a bit). Both of these price damage Nvidia’s RTX 4000 series, which begins at $1,599 for the top-tier GeForce RTX 4090 and $1,199 for the RTX 4080.

CPU Launch MSRP CUs Game clock RAM/bus width TBP
Radeon RX 7900 XTX $999 96(RDNA 3) 2300 MHz 24 GB GDDR6 (384- bit) 355 W
Radeon RX 6950 XT $ 1,099 80(RDNA 2) 2100 MHz 16 GB GDDR6 (256- bit) 335 W
Radeon RX 7900 XT $899 84(RDNA 3) 2000 MHz 20 GB GDDR6 (320- bit) 300 W
Radeon RX 6800 XT $649 72(RDNA 2) 2015 MHz 16 GB GDDR6 (256- bit) 300 W

Nvidia had actually prepared to field a 12 GB variation of the RTX 4080 in this rate variety, however a customer reaction to its possibly complicated branding and lower efficiency level triggered Nvidia to “ unlaunch” the card, with no word on when it will be re-introduced, what it will be called, or what it will cost. The 16 GB variation of the 4080 releases November 16, beating AMD’s brand-new GPUs to market by around a month.

  • AMD didn’t invest whenever comparing the brand-new Radeon cards to any Nvidia GPUs, choosing rather to compare them to their predecessors.

  • The 7900 XTX is the brand-new flagship of the series.

    AMD

  • The 7900 XT is a little action back in memory capability, bus width, clock speed, CUs, and power usage for $100 less.

When it pertained to comparing its cards versus Nvidia’s, AMD played coy throughout its discussion, thoroughly comparing the RX 7900 XTX series to the RX 6950 XT without pointing out either the RTX 3000 series or the RTX 4000 series. The 7900 XTX is stated to be “approximately 1.7 x” faster than the 6950 XT while playing video games in 4K– a 1.5 x enhancement was more typical amongst the video games AMD evaluated.

In regards to raw calculate efficiency, AMD states the 7900 XTX can approximately 61 teraflops of efficiency, while Nvidia states the RTX 4090 can 83 teraflops and the RTX 4080 of 49 teraflops. This is a very top-level efficiency number that does not inform us a lot about how the cards will compare in genuine video games (the RTX 4090 is not 70 percent much faster than the RTX 4080, according to Nvidia’s own standards). Along with the rates and absence of head-to-head 4090 contrasts, this unclear number does recommend that AMD is intending at Nvidia’s 4080 tier with these cards rather than attempting to exceed the RTX4090 This is the very same relative position that AMD has actually remained in for a couple of generations now.

A bag of chiplets

  • AMD is utilizing chiplets in the RX 7000 series, however all of the calculate resources are still in one huge die.

  • The GCD is where the majority of the hardware lives, consisting of the screen controller and media encoding engine.

  • The 6nm MCDs are for “approximately” 16 MB of Infinity Cache and memory controllers, which will make it quite easy for AMD to reduce for lower-end items.

  • RDNA 3 consists of 2 AI accelerator systems per CU.

As anticipated, the RDNA 3 GPUs will take a page out of Ryzen’s book, utilizing a group of chiplets instead of a single big piece of silicon like Nvidia is utilizing. By making a GPU out of lots of smaller sized interconnected silicon passes away, AMD can possibly lower the expense and enhance the yields of its GPUs by making sure that less silicon is tossed out or binned due to the fact that of little flaws or flaws.

Unlike in Ryzen, where the real CPU cores are divided amongst several chiplets, AMD is still putting all of the GPU’s real processing power into a single piece of silicon called the Graphics Compute Die, or GCD. Made utilizing TSMC’s 5 nm procedure, the GCD includes all of the real RDNA 3 calculate systems, plus the screen engine (for managing video output) and the media encoding and deciphering engine.

The other chiplets in each GPU are smaller sized Memory Cache Dies, or MCDs; these each consist of a 64- bit memory controller plus Infinity Cache memory. The 7900 XTX has 6 of these MCDs illuminated, while the 7900 XT has 5 of them (you can inform since the XTX has a 384- bit memory bus, while the XT has a 320- bit bus). AMD is developing the MCDs on a 6 nm production procedure, like the I/O pass away in the Ryzen 7000 CPUs.

  • AMD concentrated on enhancing RDNA 3’s ray-tracing efficiency, and each CU must can as much as 50 percent more efficiency than in RDNA 2.

  • AMD’s ray-tracing enhancements as compared in real video games.

Aside from enhancing framerates, RDNA 3 concentrates on increasing RDNA 2’s average ray-tracing efficiency. Compared to Nvidia’s RTX 3000- series and Intel’s Arc GPUs, AMD’s RDNA 2 ray-tracing accelerators dealt with less actions of the ray-tracing pipeline– particularly, they unloaded something called “tree traversal” to the general-purpose stream processors, while Nvidia’s and Intel’s ray-tracing systems dealt with traversal themselves. RDNA 3’s ray-tracing accelerators do manage this traversal, which, in addition to other enhancements, must benefit “as much as 50% more [ray-tracing] efficiency per CU,” according to AMD.

The GPU’s media encoding abilities are likewise getting an increase. Most significantly, they’ll reach the RTX 4000- series and Intel’s Arc cards by supporting hardware-accelerated encoding and decoding of AV1 video streams (approximately 8K at 60 FPS, comparable to what Nvidia and Intel deal). RDNA 2 GPUs just support hardware-accelerated decoding of AV1 videos. And AMD kept in mind that the brand-new GPUs support the DisplayPort 2.1 specification, which will make it possible for greater refresh rates on DisplayPort 2.1-capable screens when they’re more extensively offered.

Could this be a snarky reference to the laughably gigantic size of the RTX 4090 series? Probably!

Although its statement was light on efficiency contrasts, AMD took potshots at the large size and power requirements of Nvidia’s RTX 4090, showing that AMD’s 7900 XTX referral style might quickly change an RX 6950 XT without needing an updated power supply, a power cable television adapter, or a bigger case. Peak power intake increases from 330 W to 355 W– still a boost however around 100 W lower than the RTX 4090’s peak power intake and still efficient in being powered by a set of 8-pin PCIe power adapters.

On the software application side, AMD teased a next-generation variation of its FidelityFX Super Resolution (FSR) upscaling innovation, which it states is “being available in 2023” and will provide “approximately 2x more FPS vs FSR 2” at 4K resolutions. FSR 2 assisted to close the visual quality space in between the very first variation of FSR and Nvidia’s comparable DLSS upscaling tech while likewise working on more GPUs, consisting of older Radeon GPUs and lots of Intel and Nvidia GPUs. We do not yet understand whether FSR 3 will likewise be GPU-agnostic or if AMD will limit it to the latest-generation Radeon GPUs as Nvidia makes with DLSS 3 and the RTX 4000- series.

We’ll be taking a more detailed take a look at AMD’s Radeon RX 7000- series cards when they’re a bit closer to introduce.
