AMD Radeon RX 6700 XT review: The graphics card that wants to compete with the GeForce RTX 3070

Hardware News AMD Radeon RX 6700 XT Review: The Graphics Card That Wants To Compete With The GeForce RTX 3070 Posted on 03/27/2021 at 8:49 PM The year 2021 is well on the way to being interrupted by graphics card releases that nobody publishes, or almost can not buy. After a GeForce RTX 3060 with a very good price-performance ratio, which cannot be seen in stores, here is the Radeon RX 6700XT, AMD’s new GPU, which is positioned directly under the Radeon RX 6800. This new card under RDNA 2 architecture promises an excellent level of 1440p performance paired with controlled power consumption. Successful bet? In November 2020, AMD presented its new generation of graphics cards under RDNA 2 architecture with the Radeon RX 6800 and 6800 XT. A month later, the catalog was expanded to include a higher quality model, the Radeon RX 6900 XT. The manufacturer is therefore well represented in the field of high performance, but there was no mid-range model that can keep up with the GeForce RTX 3070. This happens with the 6700 XT, a card that is officially sold from 479 euros and promises a very good level of performance in 1440p. As usual in the last 6 months, the price recommended by the manufacturer is rarely found on the market. It’s actually impossible to find this model for less than € 649 right now. In short, changing graphics cards has never been so complicated and expensive. Hopefully things will return to normal by September. LDLC € 649.96 shipping € 8.95

The features of the Radeon RX 6700 XT

First, let’s take a look at the Radeon RX 6700 XT using a test model from AMD that uses the reference design of earlier RDNA2 cards. This model certainly has one less axial fan than the 6800 XT, but we find the same quality of manufacture and the same impression of solidity. The card is of course smaller than the 6800 XT, but still occupies two slots in its width. It is connected to the PC power supply via two 8-pin / 6-pin connectors. In short, nothing but very classic. We therefore find a sober and efficient no-frills design with just the Radeon logo that lights up when the card is switched on. Connectivity side, here too we stay in the standard with 3 DisplayPort 1.4 and 1 HDMI 2.1. However, the USB-C port on the Radeon 6800 XT has disappeared. In terms of technical data, the Radeon RX 6700 XT offers 40 processing units for a total of 2560 processing units. The card also offers 40 processing units for ray tracing. We also use a 7 nm engraving process. The announced base frequency is 1.59 GHz and an average of 2.42 GHz in the game. In addition, 12 GB GDDR6 RAM is clocked at 2 GHz for a bandwidth of 384 GB / s. The 6700 XT is slightly more compact than the 6800 XTAMD The Radeon RX 6700 XT is the best possible choice for gaming at 1440p. For Ultra HD, we should therefore turn more to the RX 6800/6800 XT or even the 6900 XT. For our part, we tested the card in ten games in 1440p, but also in 1080p. As a reminder, our test platform has stayed the same since we started testing the Radeon RX 6000 cards. In particular, it consists of a Ryzen 7 3800X processor and 16 GB of DDR4 RAM. All tested games were installed on an SSD Smart Access memory: more performance, but you need a Ryzen 5000. With this new generation of graphics cards, AMD is introducing the Smart Access memory function, which enables better communication between CPU and GPU thanks to PCI Express. The communication speed between the CPU and the VRAM (graphics card memory) can actually be limited in a “classic” configuration. SAM will use the PCI Express bandwidth to maximize the transfer speed between the two, resulting in a significant increase in performance. However, the use of SAM remains quite restrictive at the moment: it is indeed necessary to use a Ryzen 5000 processor, a motherboard with an AMD X570 chipset and of course a Radeon RX 6000. The performance gain announced by AMD while gaming also remains weak, especially in Ultra HD. According to the manufacturer, it would be around 12% for Forza Horizon 4, for example, but stay closer to 2 to 5% in most games. However, the idea is pretty good and makes another argument in favor of the excellent Ryzen 5000 processors.

A very comfortable card in 1440p … but without ray tracing

In terms of performance, the Radeon RX 6700 XT keeps its promises in 1440p in rasterized games (i.e. those that don’t use ray tracing) and in most cases allows for reaching and exceeding 60 frames / second with the level of detail set to the maximum. Only Red Dead Redemption 2 and Cyberpunk 2077 (without ray tracing) barely exceed 50 FPS but are still playable while looking nice. Incidentally, we achieve more than 170 FPS with Doom Eternal and Wolfenstein Youngblood (always the best students), while CoD: Modern Warfare and Warzone rise above 90 FPS. On the other hand, it’s a different story and performance that undeniably collapses once you turn on ray tracing for the few compatible games. Experience the 29 FPS in control or the 45 FPS in Metro Exodus. An observation that we already made on the Radeon RX 6800 XT and 6900 XT and that will certainly not change until AMD installs DLSS-like technology on its cards. At 1080p, rasterization performance increases, with the vast majority of games exceeding 90 FPS. If you’ve got a 244Hz screen, you’ll appreciate the ultra-smooth flow of a Doom Eternal or Wolfenstein Youngblood that surpasses 200 FPS. If we ignore the once again disappointing ray tracing performance, the Radeon RX 6700 XT is on par with the GeForce RTX 3070 in terms of performance. A good point, all the more. The AMD card is “officially” € 40 cheaper than the Nvidia card. Nevertheless, the RTX 3070 has the decisive advantage of offering ray tracing and DLSS. History therefore tends to repeat itself …

A good point for consumption

In terms of consumption, AMD announces an average TDP of 230 watts for the Radeon RX 6700 XT, which is 70 watts less than the Radeon RX 6800 XT, which delivers up to 300 watts, and 10 watts more than the GeForce RTX 3070 ( TDP) 220 watts). In practice, we use an average of 215 watts for Metro Exodus. A number that remains very good. In idle mode, ie under Windows 10 with office automation or surfing the Internet, the card consumes around 35 watts. The new graphics card from AMD is also a very good student on the temperature side and does not exceed 80 ° C under full load (here with Metro Exodus). All of this comes with a very acceptable level of noise, with fans that only run in-game (hence, it remains completely silent in office automation), and a breath that is very inaudible as long as your case is adequately insulated and ventilated. Notes + Positive points Very good performance level in 1440p A solidly designed card Controlled energy consumption – Negative points Almost nonexistent ray-tracing performance in stock We expect the equivalent of DLSS In the end, the Radeon RX 6700 XT is a very good mid-range card that in 1440p delivers a good level of performance and at the same time is very efficient from an energetic point of view. As long as you can find it at its “normal” price – 479 euros – it is therefore highly recommended, even if the ray tracing performance leaves a lot to be desired. Because yes, as long as AMD does not offer an equivalent to Nvidia’s DLSS, the level of performance will be strongly influenced. Fortunately; The “Fidelity FX Super Resolution” function is expected to be implemented in software on all current AMD GPUs and will be available this year. Nevertheless, let us end with an observation that is becoming more and more problematic: the lack of inventory, which is a heavy burden on the sector and leads to a sharp rise in prices. A situation that should last at least until the beginning of September. LDLC offers € 649.96 Shipping € 8.95 From Jiikaa, Journalist MP
