Radeon RX 6600: AMD Targets 1080p Gamers On A Budget
As was the case with the Radeon RX 6600 XT, AMD itself won’t be making its own reference cards for retail. Instead, AMD is leaning on its board partners for Radeon RX 6600 designs and there will be quite a varied selection from all of the usual suspects, like PowerColor, ASUS, Sapphire, XFX and others. Take a peek at the Radeon RX 6600’s main features and reference specs below, and then we’ll dig in a little further and see what this card is all about...
Radeon RX 6600 Features & Specifications
The table above shows how the new Radeon RX 6600 stacks up to its counterparts in AMD’s GPU line-up. As you can see, the Radeon RX 6600 is based on the same physical GPU (Navi 23) as the higher-end Radeon RX 6600 XT, which is manufactured on TSMC’s 7nm node and is comprised of roughly 11.1 billion transistors. A quartet of compute units are disabled on the Radeon RX 6600, however, which brings the Ray Accelerator count and total number of stream processors down to 28 and 1,792, respectively.
Radeon RX 5600 XT GPU, the Navi 23 chip powering the Radeon RX 6600 has a somewhat smaller die size. It also has fewer compute units (and fewer stream processors as a result), but because it is based on the newer RDNA 2 architecture, it incorporates Ray Accelerators and 32MB of Infinity Cache to enable hardware accelerated DXR support and higher effective memory bandwidth, at least when the Infinity Cache comes into play. The newer Navi 23 GPU is also capable of hitting much higher clock speeds than the previous-gen 5600 XT, so the 6600 ends up offering higher compute performance and fillrate as a result.
The Radeon RX 6600’s typical board power is rated for 132 watts, but board partners will be offering cards at different power levels according to AMD.
It features a dual fan cooler, with multiple heatsinks and copper heatpipes, but it is significantly smaller and lighter than some higher-end cards, like PowerColor’s own Red Devil series, for example.
The PowerColor Radeon RX 6600 XT Fighter’s clock speeds are in-line with AMD’s reference specifications, which call for a 2,044MHz game clock and a 2,491MHz boost clock, and it features the same 8GB of GDDR6 memory as well.
RGB accents to be found either, and the card requires only a single PCIe power connector. The output configuration consists of a trio of full-sized DisplayPorts (v1.4) and a single HDMI port (v2.1). Overall, versus higher-end (and more expensive) graphics cards, the PowerColor Radeon RX 6600 Fighter’s design elements are somewhat more subdued. The design is also somewhat shorter and thinner too; this card is only two slots wide, versus the 2.7 - 3 slot width of many higher-end offerings.
And with that, it’s time to plug in the PowerColor Radeon RX 6600 and see how she performs...
