New AMD RX 6500 XT and RX 6400 GPUs Listed With 4GB of GDDR6

According to a new ECC listing, AMD appears to be developing three new graphics cards that might come to market soon (via @Momomo_us). A PowerColor listing from the Eurasian Economic Commission (ECC) reveals the RX 6500 XT, RX 6400, and BC-2235 graphics cards, the latter of which is likely a mining card similar to the recently discovered XFX BC-160. As always, ECC listings are often placeholders for potential products, so they aren't a guaranteed indication that a product will come to market. Take this information with a grain of salt, in other words.

The listings are bare of most specifications, though we can glean the memory capacities via the product name. For example, the BC-2235 mining card appears to come with 10GB of GDDR6 memory while the RX 6500 XT and RX 6400 both come with 4GB of GDDR6 instead.

Based on the memory specs alone, the RX 6500 XT and RX 6400 should be AMD's entry-level products in its RX 6000-series gaming cards lineup and will probably compete with Nvidia's rumored desktop RTX 3050 graphics cards. 4GB of VRAM might be sufficient for medium to high settings at 1080p, but don't expect a lot from these cards. We've already seen games such as Battlefield 2042 rip right through 6GB of memory at 1080p ultra quality settings on midrange cards like the RTX 2060.

We don't know the expected core counts, core frequencies, or anything other fine-grained details, but we suspect the RX 6500 XT will be a good step below the RX 6600 in terms of performance and power draw, probably landing around the 100W mark, perhaps even less.

The RX 6400 should be even more of a power sipper, with the ECC listing also reporting an RX 6400 LP (low profile) edition card. These cards will be designed to slot into half-height PCIe chassis with a very compact PCB layout. Cards like this don't typically use supplementary power, so we can expect the RX 6400 to have a 75W power limit or lower.

Finally, that BC-2235 looks rather curious. 10GB of GDDR6 memory would suggest a scaled down Navi 21 GPU with only five of the potential eight memory interfaces active. That would yield a 160-bit memory interface with 2GB GDDR6 chips, but then there's the name. Based on the XFX BC-160 naming, BC is for "Blockchain Compute," the "2" indicates a second generation (RDNA 2) GPU, and the final 235 would be... the hashrate? But there's no way a card like this would hit 235 MH/s in Ethereum, so more likely the "22" is for RDNA2. Based on the RX 6700 XT and RX 6600 XT mining performance, we're probably looking at around 35-40 MH/s after tuning.

    Based on the last generation of 4GB GPUs, anything intended to be a meaningful upgrade over those really should have 6GB.

    If they put only 4GB on them to make them unusable for ETC mining, I hope they at least put a full 4.0x16 interface so the GPUs can more effectively offset their memory handicap using system memory.

    Navi 24 based gpu already down to x8 only. Don't be surprise if AMD will limit this further to x4 lol

    Well. Fast enough for mice sweeper! Best gpu you can most probably buy below $500 ;)
    These are the low, low end gpus that is sure, but Maybe they cost less also. It is nice to see GPUs that cost only $499 for a while...

    Honestly if they can get RX 580 performance on a low profile 75w card, that would be a very nice upgrade for many people with power supply or chassis limitations.

    I have a 650W Titanium-rated PSU and turned down a friend's RX580 because I like my practically silent GTX1050 more than the RX580's extra performance. I'd love to have something more current-gen with 6GB of VRAM in a 75W trim.

    The only way to get more than 4GB of VRAM is to use 2GB chips, since the 6600XT is already down to a 128-bit bus. Unless of course AMD decided to neuter the interface even more down to say 64-bit.

    4Gb.......I'm not that desperate.
    Not ready to say 'Uncle'.
