AMD Radeon RX 6600 XT: announcement, details, information and features of the new GPU

AMD Radeon RX 6600 XT

Also this time the rumors have proved correct anticipating the announcement of the AMD Radeon RX 6600 XT, now official with launch date set for 11 August. So, there is little time left for the arrival of a mid-range video card from $ 379 which, becoming the entry level of the AMD RDNA 2 series, takes the field to oppose the NVIDIA GeForce RTX 3060 with a recommended price higher than 50. dollars but with 15% more rasterization power, at least on paper.

Paying it right, however, won't be easy. While the prices of gaming video cards have dropped, they are still high and it will not be possible to buy a card directly from AMD. This is because although the company has released images and data of a single fan reference model, perhaps intended for the OEM sector, it seems that this will not be put on sale.

We nevertheless take the basic design as a reference, presumably similar to that of the cheaper custom models.

Hardware features

The AMD Radeon RX 6600 XT is equipped with a Navi 23 XT chip with 11.06 billion transistors on a 237 mm2 die. It is not, therefore, a castrated version of a superior model but a whole new GPU with 32 compute units, which are 8 fewer than those of the AMD Radeon RX 6700 XT. They are therefore 20% lower and also involve 8 less ray accelerators, since each compute unit contains 1. Of course, we are also talking about a saving of 20.8%, but in certain performances it is probable that the drop in performance is greater than these percentages.

Also because despite the boost frequency reaches up to 2589 MHz, very high for this band and even higher than the 2581 MHz of the older sister, we must take into account characteristics lower than 360 degrees. The new entry level proposal is in fact satisfied with 8 GB of memory which, however pushed to 16 Gbps, have to deal with 128-bit buses and a bandwidth of 256 GB / s. In addition, the Infinity Cache goes from 96 MB to 32 MB.

But we are talking, we have said, of a solution designed for 1080p with high framerate, where 8 GB of GDDR6 memory are amply sufficient. Among other things, they contribute to lower consumption that stop at 160 W of Typical Board Power, allowing the board to stay wide in a configuration with a 500 W power supply. This at least talking about the reference design which, although not sold separately, could appear in some of the pre-assembled devices arriving at the beginning of August with an AMD Radeon RX 6600 XT inside.

Regardless of the type, however, the cards will not lack all the wealth of features and software built in recent years by AMD. We clearly refer to Smart Access Memory, Radeon Boost, Radeon Chill, Contrast Adaptive Sharpening, color filter management and all the various options of a complete software suite also from the point of view of system statistics, manual and automatic overclocking, video capture. , streaming and support.

Performance
Enough to make a perfect GPU interesting for those looking exclusively at the report between price and number of frames on the screen. Less for those who look at ray tracing given the small number of ray accelerators and the lack of cores dedicated to upscaling. But the new Radeon can take advantage, like practically every existing video card, of AMD FidelityFX Super Resolution technology which, while involving a loss of detail, returns an image of excellent quality in relation to the performance gain.

Regardless of the 'upscaling however, the 1080p promise of the AMD Radeon RX 6600 XT, without ray tracing but with the graphics settings at maximum, is that of 164 FPS in Battlefield 5, 155 in DOOM Eternal, 176 in the recent Resident Evil Village, 97 with Horizon Zero Dawn, 96 in Borderlands 3 and 83 with the heavy Cyberpunk 2077. Moving on to the competitive ones we go up to 186 FPS with Apex Legends, 289 with DOTA 2, 441 with Tom Clancy's Rainbow Six Siege and 553 with Valorant. Sufficient therefore to take advantage of the connectivity which, through three DisplayPort 1.4 and an HDMI 2.1 output, is more than enough to fully exploit high-speed monitors and setups consisting of multiple screens. ! function () {"use strict"; window.addEventListener ("message", (function (e) {if (void 0! == e.data ["datawrapper-height"]) {var t = document.querySelectorAll ( "iframe"); for (var a in e.data ["datawrapper-height"]) for (var r = 0; r We are convinced that in the coming months there will also be models pushed for a GPU that could reach record frequencies seen the combination of a high factory clock and fewer compute units ready to heat up.
