AMD Rumored to Announce RX 7800 16GB & RX 7700 12GB in August, Release Planned for September

AMD announced RDNA3 last year in early November. Initially, we only saw the Navi31 GPU used on the 7900 series of Radeon RX GPUs. Navi33 came with the RX 7600, however, we are still yet to see the mid-ranged Navi32 SKU. Moore’s Law Is Dead alleges that AMD will announce the Radeon RX 7800 and RX 7700 based on Navi32 in August.

Radeon RX 7800 & RX 7700

Using the top Navi32 configuration with 60 Compute Units, the Radeon RX 7800 packs 16GB of 19.5Gbps memory. This amounts to 624GB/s of effective bandwidth over a 256-bit memory interface. The RX 7800 replaces RDNA2’s RX 6800, while supposedly being more efficient. The suggested TBP by MLID is rated at 260W, not much higher than its last-gen competitor.

Similarly, the RX 7700 will host a cut-down Navi32 chip boasting 48 or 54 CUs depending on yields. Alongside that we see 12GB of G6 memory which over a 192-bit interface sums up to 468GB/s of effective bandwidth. The RX 7700 should feature 12GB of memory which is 2GB more than the RX 6700 Non-XT.

Do note that the naming of these GPUs can be changed as AMD is currently shuffling its RDNA3 lineup. We have seen significant price cuts with the RX 7900 XT dropping to as low as $700. If these changes persist, AMD may rename the SKUs to better adjust to the environment.

The source has confirmed that AMD is planning to unveil 2 GPUs based on Navi32 during Gamescom in August. Gamescom is planned for round about the last week of August, so expect a release date in early-mid September.

Radeon RX 7900, Hybrid Navi31 x Navi32

A while back, we saw MLID leak AMD’s plans for a hybrid chip using both Navi31 and Navi32. The way this design works is that AMD is placing a Navi31 GCD on a Navi32 package, with 4 MCDs instead of 6. Since this SKU also features 70 Compute Units, the Navi31 GCDs used are mostly defective chips that didn’t qualify for use in actual Navi31 products.

As the supply of this chip will be limited, AMD is currently thinking of making an RX 7900 based on this design. MLID claims that the RX 7900 will have stock similar to the RX 6700 10GB, which has not been reviewed by many YouTubers due to supply constraints. Though, AMD is not ready to launch this SKU just yet as the market has changed drastically over the past 2 months.

RX 7900 Clarification | MLID


The wait is not long until we see these GPUs fall into the hands of leakers and testers. Stay tuned at Appuals as we’ll keep you updated in that regard. The pricing structure of Navi32 is quite simple, since AMD just needs to slot in these GPUs with its current RDNA3 lineup.

MLID says that a few pricing differences can be made to enhance AMD’s market share. Put simply, AMD can revise the MSRPs of its current RX 7900 series and then adjust Navi32 somewhere in between. The currently expected price for the RX 7800 is $549 with the RX 7700 coming in at $449.
