Latest AMD Radeon RX 6600 leak points to an October 13 launch with 28 CUs and 8 GB GDDR6 VRAM

The Radeon RX 6600 first leaked months ago, with the RX 6600 XT launching in July. Since then, VideoCardz has leaked RX 6600 marketing assets, confirming that AMD's partners will sell custom models. Now, VideoCardz has shared information about the RX 6600's launch and several specifications to boot.

Supposedly, AMD and its partners (AIBs) will deliver the first RX 6600 GPUs to press outlets on October 4, with samples shipping as early as September 29. However, detailed tests and reviews cannot go live until October 13 at 09:00 EDT (UTC 13:00). The same embargo time applies to AIBs announcing 'product branding and pricing' on their websites and social media. VideoCardz speculates that the RX 6600 may launch on October 13, as well.

The table embedded below shows how AMD's cheapest RDNA 2 stacks up against the rest of the series. With 28 compute units (CUs) or 1,792 computing units, the RX 6600 has 87.5% of the CUs that the RX 6600 XT has. The RX 6600 matches its XT sibling in terms of VRAM, Infinity Cache, I/O and 'featured tech', too. Hence, the RX 6600 has 8 GB of GDDR6 VRAM and 32 MB of Infinity Cache, along with HDMI 2.1 VRR and DisplayPort 1.4 DSC connections.

PCIe 4.0 is supported, as is DirectX 12 Ultimate, ray tracing, and AMD's software stack. According to the slide below, these include AMD FidelityFX Super Resolution (FSR), AMD FreeSync, Smart Access Memory (SAM) and Radeon Anti-Lag. Unfortunately, AMD will not offer a reference graphics card, shown above. Presumably, the render is only for illustrative purposes on AMD's part. Instead, only AIBs will sell the RX 6600, as is the case with the RX 6600 XT. Pricing remains unknown at this stage, but we imagine that it will be between the US$300 and US$350 mark.
