There are just again new details about AMD’s entry-level graphics cards Radeon RX 6500XT and also the smaller RX 6400 with RDNA2 GPU leaked. The latest information on Navi24 comes from Citizen on the Bilibili social network, and it could well be true if you put all the pieces of the puzzle together and also get AMD’s announcement about graphics hardware at CES right. What we do know is that AMD is preparing at least two new graphics cards based on the Navi24 GPU, the Radeon RX 6500XT and the Radeon RX 6400.
Both graphics cards are obviously aimed at the entry-level segment, and the larger of the two, theRX 6500XT, will then surely compete directly with the upcoming GeForce RTX 3050 TI and Intel’s ARC A380, while the RX 6400 will have to compete against the smaller GeForce RTX 3050 and Intel’s ARC A350 graphics cards.
The AMD Radeon RX 6500 T will use the full-featured Navi24 XT GPU, which we already know as the “Beige Goby”. It is the smallest AMD GPU from the RDNA 2 series and it will only have a single SDMA engine. The chip is said to have 2 shader arrays for a total of 8 WGPs and a maximum of 16 compute units. AMD uses 64 stream processors per compute unit, so the total number of cores on the Navi 24 GPU is 1024, which (who’s surprised) is exactly half of the Navi 23 GPU, which offers 2048 stream processors in 32 compute units.
In addition to the number of cores, each shader array is said to have 128 KB of L1 cache, 1 MB of L2 cache, and 16 MB of Infinity Cache (LLC). As expected, the GPUs will have a 64-bit bus interface and will be used in low-end Radeon RX 6500 or RX 6400 series parts. It’s safe to assume that AMD’s Navi 24 will reach very high clock speeds and might even exceed the 2.8 GHz limit out of the box. In terms of pure specs, the Radeon RX 6500 XT graphics card will feature 1024 cores and have 4GB of GDDR6 memory.
If current information is to be believed, the card is also said to be incapable of working with any mining algorithm, especially ETH. The top model will have a TDP of just over 75W, so it will still need an external power connection. This then fully coincides with things I reported months ago. The card is expected to hit the market in mid-January after being announced at CES, which would make perfect sense.
The second card in the Navi24 lineup is the Radeon RX 6400, which is likely to be based on a slightly stripped down ‘XL’ chip with 768 cores. The card will certainly retain the 4GB of GDDR6 memory, but will feature slightly lower clock speeds in exchange, though they could still be in the 2.5GHz range or above. One could assume that the RX 6400 could then be fed directly from the PCIe slot thanks to its TDP value of under 75 watts. It’s rumored to be March 2022, as that’s when you can counter Intel’s ARC Alchemist GPU in this segment.
I don’t want to speculate about the prices, but both cards won’t be priced below 200 Euro (rather the opposite) and the RX 6500XT might even come out with a leading three. Not a good premonition, but I alone lack faith in a significant improvement in the tight price situation.
