With the Radeon RX 6600 released today, AMD rounds out the Navi portfolio even further down the line. Since there are once again no reference cards (AMD is following NVIDIA’s lead here with the GeForce RTX 3060), today’s launch article will thus once again use a board partner card. It will be exciting to see if the XFX RX 6600 SWFT 210 SPEEDSTER 8GB tested today matches what I had already tested as an emulated card some time ago.
Of course I don’t want to spoil too much in advance, but I can give myself a pat on the back in advance. You will see in a moment how much this was already “On Point” at that time. But first I dedicate myself to the chip as such and then also to the test sample, which this time comes from XFX and was adapted quite cost-reduced for the market to be able to meet the MSRP.
But before we really start, we have to write about the availability, because this will also influence the price. Since all this can’t be predicted, I have to consult the MSRP of 339 Euro, even though you’ll hardly see anything in this price range in the shop window. At least, certainly not for everyone who would like to buy such a card. AMD’s price is based on the GeForce RTX 3060, which is certainly about right in terms of performance. Only the rest is done by the dear retailer with a gesture of generosity.
And for those who don’t know what I mean by emulated card, here’s the link again to remind you and compare later: AMD Radeon RX 6600 Non-XT Benchmarks – Equal to GeForce RTX 3060?
Preliminary remark on the test sample
The title also says something about small hurdles, and I’ll have to write about that in a bit more detail when we get to the teardown. A lot of things already went wrong out-of-the-box and I had to play MacGyver once again with hot glue and some inspiration. The left fan above the GPU (the most important one, because the tacho signal is also tapped here) already said goodbye to the eternal hunting grounds with an audible crackling and the dreaded smell of dead electronics when it was switched on for the first time. I couldn’t find a replacement in a hurry, so I had to modify the card a bit.
By the way, I am very satisfied with the result of my transplantation and also the construction diary in the context of the teardown will provide the necessary transparency, so that everything is correct. In the meantime another card came from Powercolor and I can surely publish a counter test this week. Until then, you’ll have to live with my “Frankenstein mod”, but gaming performance certainly won’t be lacking. Problems are meant to be solved.
The Radeon RX 6600 with Navi 23
The AMD Radeon RX 6600 Non-XT relies on the Navi 23 XL GPU, which only has 28 instead of 32 compute units or 1792 instead of 2048 stream processors. Thus, the card is already at a disadvantage of about 12 percentage points on paper, if the clock is set at the same level. The card also features, like the XT, 32MB of Infinity Cache and 8GB of GDDR6 memory running over a 128-bit wide bus interface. The Navi 23 XL GPU itself measures 237 mm² and consists of 11.06 billion transistors.
In contrast to the GT, the memory speed only uses 14 Gbps modules from Hynix with 1750 MHz (instead of the usual 2000 MHz). But the memory allows overclocking up to 1900 MHz without any problems. However, the GPU is still not the smallest chip in the RDNA 2 family, as Navi 24 is still expected here for the absolute entry-level range.
The XFX card is a real lightweight with just under 640 grams, the front is dominated by two current 9.5 cm fans, whose design we already know from the other XFX cards. The rest is ABS in black with no color accents and no illuminated logo on the top. Saving is the order of the day and so everything remains dark for the time being. So it’s not a visual thrill, but it’s not a complete derailment either. It’ll be fine, if the price is right.
The card is a pure dual-slot design and requires an additional 0.4 cm for the rear planking with a backplate. The cooling fins are vertical and on the top we see a single 8-pin power supply connector. The rest, however, is completely unspectacular.
The backside of the board is covered by a backplate, as already written. The air opening also reveals that the board with its 18 cm length is quite a bit shorter than the 24.5 cm long card (slot bracket to card end). The height, however, is more generous at 12.5 cm.
The slot bracket is closed, carries 1x HDMI 2.1 and three current DP connectors. The USB Type C is omitted. The whole thing is powered via an 8-pin socket. More about this on the next page in the teardown.
The screenshot from GPU-Z then provides information about the remaining data of the card:
Again, I have a table for all statisticians among you, before it really gets going from the next page on.
