AMD Reveals the Radeon RX 6000 Series, Coming November 18th

Last modified on October 30, 2020

Getting ready to close out a chief month of bulletins for AMD – and to open the door to the following technology of architectures all the process by which by technique of the firm – AMD wrapped up its last keynote presentation of the month by saying their Radeon RX 6000 collection of video playing cards. Hosted as quickly as additional by AMD CEO Dr. Lisa Su, AMD’s hour-prolonged keynote revealed the first three substances in AMD’s new RDNA2 structure video card household: the Radeon RX 6800, 6800 XT, and 6900 XT. The core of AMD’s new excessive-cease video card lineup, AMD formulation to manufacture combat with the best of the best out of arch-rival NVIDIA. And we’ll acquire to survey first-hand if AMD can retake the excessive-cease market on November 18th, when the first two playing cards hit retail cabinets.

AMD’s impending video card begin has been a chronic time coming for the firm, and one they’ve been teasing specifically closely. For AMD, the Radeon RX 6000 collection represents the stop finish results of efforts from all the process by which by technique of the firm as all individuals from the GPU structure personnel and the semi-custom-made SoC personnel to the Zen CPU personnel has performed a neutral in creating AMD’s newest GPU skills. The complete whereas, these new playing cards are AMD’s best chance in now no longer decrease than half of a decade to at closing defend as a lot as NVIDIA at the excessive-cease of the video card market. So understandably, the firm is jazzed – and in higher than simply appropriate a advertising formulation – about what the RX 6000 formulation.

Anchoring the new playing cards is AMD’s RDNA2 GPU structure. RDNA2 is launching shut to-concurrently all the process by which by technique of consoles and PC video playing cards subsequent month, the place this might perchance even be the backbone of some 200 million online game consoles plus limitless AMD GPUs and APUs to succeed in profit. Accordingly, AMD has pulled out the full stops in designing it, assembling an structure that’s on the lowering-fringe of technical components take care of ray tracing and DirectX 12 Final toughen, the full whereas leveraging the moderately a pair of issues they’ve realized from their successful Zen CPU architectures to maximise RDNA2’s efficiency. RDNA2 shall be uncommon in that it isn’t being constructed on a brand new manufacturing route of, so coming from AMD’s earlier RDNA (1) structure and linked video playing cards, AMD is counting on architectural enhancements to reveal just about all of their efficiency options. In precise truth, it’s AMD’s RDNA2 structure that’s going to assemble or destroy their new playing cards.

Over the approaching months, RDNA2 will filter down into an growing amount of AMD chip designs. But for now, inside the PC set, AMD is beginning up with enthusiast-stage video playing cards. The main RDNA2 GPU out of the works is Navi 21 – AKA “Mammoth Navi” – which AMD could perchance be the utilization of as a result of the premise of a trio of video playing cards. These are the Radeon RX 6900 XT, 6800 XT, and 6800 respectively. With these newest playing cards, AMD is aiming squarely at NVIDIA’s recently-launched GeForce RTX 30-series lineup, aiming to fulfill (or beat) the RTX 3090, 3080, and 3070 respectively. Suffice it to voice, AMD hasn’t been capable of evaluate NVIDIA’s prime playing cards for a number of years now, so these are very brave claims from an organization that has re-realized strategies to vary into very brave inside the closing 5 years.

As in the present day time’s announcement is now no longer a fats tech deep dive – take care of the Zen three announcement, the deep dive will attain nearer to begin – AMD is best sharing some excessive-stage specs of the new playing cards. But with knowledge on the amount of CUs, reminiscence toughen, and vitality consumption now in hand, we bear now an accurate recommendation of what AMD is bringing to the desk, and why they bear referring to the RX 6000 collection will as quickly as additional assemble them absolutely-aggressive at the excessive-cease.

Radeon RX 6900 XT

Amongst AMD’s video card stack, the firm is taking a extraordinarily an identical tack as NVIDIA. So even though the RX 6900 XT is technically their flagship share, at $999 or now no longer it's aloof in a an identical “more money than sense” class as a result of the RTX 3090 – which is to voice that AMD is involving to payment an accurate prime price for the card. Because it’s primarily primarily based on a truly-enabled (and positively closely binned) Navi 21 GPU, it’s the hardest share for AMD to perform, and thus the rarest. How uncommon stays to be seen, however as Navi 21 is positively an enormous chip as a result of the the 26.eight billion transistors housing 80 CUs and 128MB Infinity Cache (additional on that later), I don’t question AMD to be flooding the market with 6900 XTs any time quickly.

At any price, the card could perchance be the fats Navi 21 skills. All 80CUs shall be enabled, and because of the AMD’s efforts in optimizing the RDNA2 structure for clockspeeds, this might perchance additionally bear a sport clock of 2015MHz and a peak turbo clock (improve clock) of 2250MHz. Assuming that AMD hasn’t carried out one thing too crazy with the RDNA2 structure, this means that the card could perchance perchance bear a median FP32 shader throughput of round 20.6 TFLOPS, higher than double the throughput of the RX 5700 XT – and simply appropriate per AMD’s needs to double their efficiency over the RX 5000 collection.

On the reminiscence side of issues the card comes with 16GB of GDDR6. AMD is now no longer formally disclosing the reminiscence clockspeed, however primarily primarily based on current tech inclinations we’re waiting for that GDDR6 to be operating at 16 Gbps/pin (which AMD has since confirmed). In the period in-between, primarily primarily based on different AMD slides, it appears take care of this reminiscence is linked to a 256-bit reminiscence bus, which might give the card a complete reminiscence bandwidth of 512GB/sec. That is basically a cramped anemic for a flagship video card, and is the place AMD’s new Infinity Cache skills will attain into play.

Ultimately, AMD says that the card could perchance perchance bear a Total Board Energy (TBP) of 300W. At a time when ASIC designers in all places are struggling to defend vitality consumption in check – and when even NVIDIA’s prime playing cards now hit 350W – a 300W TBP is a chief reveal. No longer best is it doubtlessly a aggressive benefit for AMD, but it surely formulation they haven’t desired to spice up their TBP versus their outdated excessive-cease card, the additionally 7nm-essentially primarily based Radeon VII.

With all of that talked about, alternatively, some expectation administration is in painting. Despite the undeniable fact that AMD is evaluating the RX 6900 XT to NVIDIA’s RTX 3090, there are a pair of potential gotchas involved. We’ll destroy down AMD’s specific efficiency claims and benchmark slides later, however suffice it to voice and as AMD is pitching issues now, if the RX 6900 XT can match the 3090, it’s going to be at the very prime fringe of the AMD card’s efficiency profile, overclocking integrated. Which might perchance scamper hand-in-hand with the heavy binning talked about earlier.

Radeon RX 6800 XT

Intriguing down the highway we bear now the Radeon RX 6800 XT. Based totally on an attractive cut-down Navi 21 GPU, proper here is the AMD card that mere mortals can bear the funds for. At $650 it’s aloof pricey, to voice the least, however vastly much less so than the $1000 6900 XT.

Out of the field, the RX 6800 XT comes with 72 CUs enabled. Blended with clockspeeds very similar to the RX 6900 XT – a sport clock of 2015MHz and a seize clock of 2250MHz – and pending extra technical little print from AMD, the card might additionally aloof sensible round 18.6 TFLOPS of FP32 shader efficiency. Relative to the RX 5700, proper here is simply appropriate beneath 2x the efficiency of AMD’s closing-gen essential card.

A amount of than the low value in CUs, per AMD’s specs there are actually no longer each different distinguished variations between the RX 6800 XT and RX 6900 XT. The additional low cost card aloof comes with 16GB of GDDR6 reminiscence, and I question it’ll be clocked at 16 Gbps/pin as neatly, giving it an anticipated complete bandwidth of 512GB/sec. Augmenting this, take care of every of in the present day time’s playing cards, shall be 128MB of AMD’s Infinity Cache. In the period in-between the card’s TBP carries the similar 300W rating as a result of the 6900 XT as neatly.

AMD is positioning this card instantly in opposition to NVIDIA’s RTX 3080; and by no means like the 6900 XT, there are actually no longer any asterisks to speak of proper right here. So if AMD can reveal on their claims, then this 6800 XT shall be doing so simply appropriate out of the field. Wherein case, assembly the 3080 in efficiency and perchance beating it in vitality consumption can be a mammoth decide for AMD and the RDNA2 structure, and a sign of how far they’ve attain inside the previous couple of years.

Total, given AMD’s efficiency expectations and pricing, together with the anticipated competitors, it’s unsurprising that AMD led with this card in the present day time for the Radeon keynote. It’s technically now no longer the flagship, however take care of the RTX 3080 on NVIDIA’s side, it’s going to be the card that garners the most consideration.

Radeon RX 6800

Will doubtlessly be the last card in AMD’s new product stack, alternatively, that may garner the most in product sales. Rounding out the Navi 21 trio of playing cards we bear now the Radeon RX 6800, a extra cut-down Navi 21 share that trades off a fall in efficiency for decrease vitality consumption and a extra reasonably priced $579 impress.
