    so now 5500=6500=580

    As if this poor card needed any more memory.
    Anyone using it will be limited to 1080p, who needs more than 4Gb at that resolution?
    With the price increase you're better saving and getting RX6600 instead.

    It's beneficial for this card as it'll reduce instances of requiring loading from system ram over its 4x PCIE bus link should it run out of vram which for systems without pcie4 is very detrimental on performance.

    Might be useful to avoid the GPU to go over the PCI bus to get data from ram.
    Considering that this card only has PCIe 4.0 x4, it's probably a good thing

    This card being so limited by the bus actually needs 6-8gb to reduce that bottleneck, could be a decent card now but the added price will ruin that.

    Yes the card were limited by their memory...
    And now we found lot of game with above 4g of VRam use in 1080, so this is something AMD should have done at start (even more with ram price dropping).
    But also this card were limited by other "chunk too much" as the video encoding/decoding, the PCIe X4 wiring...

    I agree with you, RX6600 8g is at 299 Euro, and RX6500XT 4g is at 259... For 40 Euro my choise would be easy, maybe the RX6500XT 8g is a bit too late.

    memory amount dont help when bus is just 64bit. Its just too slow to load and upload anything from memory. Thats why older tech is still 10x better than these low end shitties

    When I saw a 64bit memory bus, it felt like it was 2005 all over again lol.
    This card would be a solid-ish card if it was at least 128bit. I'd buy one for my 1080p gaming HTPC.

    Agree^....The good old RX 580 can still hold it's own @1080p (fine wine)

    This card is crippled internally.

    I gave my rx 480 4gb nitro to my gfs brother.
    Its flashed with a 580 4gb bios. Rather inpressive how well it still games at 1080p. Usually always high settings and pushing 40-60fps in the games he plays.

    As others have pointed out, a 4GB 480/580 holds up fairly well today. Data has to swap in and our just as often (actually, probably more often since I don't think that architecture compressed data as much) yet it doesn't cripple performance because the memory is fast enough to swap the buffer, and the PCIe bus is wide enough to feed more data.
    If the 6500XT only had a wider memory bus, that wouldn't solve the problem because the data feed over PCIe would still be too slow. I don't think Sapphire has much control over this.
    If the 6500XT only had more PCIe lanes, that also wouldn't be enough because the memory bus is too narrow to swap data in and out quickly enough. Sapphire definitely has no control over this.
    But with 8GB instead of 4GB, it doesn't have to feed data as often and it doesn't have to constantly swap out its buffer. The memory bus is still too slow but there ought to be a noteworthy performance increase just simply because it's not wasting so many cycles swapping the buffer. This is a reasonable option that Sapphire can actually take action on.

    Now the only question is: what will it be priced at, because the original 4GB was severely overpriced.

    EDIT:
    From what I recall, this GPU had reasonable performance so long as it didn't run out of VRAM.

    good to see, really should have launched with an 8gb sku.

    also as for how they got 8gb, 4GB chips are already available( gddr chips are 32bits wide), and are used mainly on quadro/tesla and firepros/instinct cards

    When it comes to upgrades, most of the systems where this would be used do not support PCIe4 due AMD releasing B550 very late and 3100/3300 never really existed. Zen3 also lacks cheap SKUs so this card really needs cheap intel PCIe4 capable CPU to save it from complete disaster...
    I guess 6500 is what happens when AMD overestimate how many laptop GPUs they can sell.
