For months now, there has been speculation about AMD’s next generation of GPUs – the RX 8000 series. While AMD hasn’t officially provided any specs, some recent leaks and rumors and giving us a good idea of what to expect either later this year or at the start of 2025 when the RX 8000 series release date likely comes around.
The latest post by a well-known leaker mentions the amount of Infinity cache that the upcoming GPUs will feature. Infinity Cache has been around since AMD’s RDNA 2 GPUs and will again be a feature of the upcoming RDNA 4 line-up. It is referred to as a “massive bandwidth amplifier”, increasing bandwidth performance with lower power and lower latency.
RDNA 4 GPUs will feature 48MB to 64MB Infinity Cache, rumor says
As per the latest post on X by Kepler_L2, it looks like the upcoming GPUs will have an infinity cache ranging from 48MB to 64MB. More specifically, the higher-end cards (two of the models) will feature a 64MB cache, and the entry-level card will feature a 48MB cache.
When RDNA 3 GPUs were released, they featured the new second-generation Infinity Cache. So, naturally, the upcoming 8000 series GPUs should launch with third-generation cache. For comparison, the current 7000 series Infinity Cache values look like this:
| GPU | AMD Infinity Cache Technology |
|---|---|
| RX 7900 XTX | 96 MB |
| RX 7900 XT | 80 MB |
| RX 7900 GRE | 64 MB |
| RX 7800 XT | 64 MB |
| RX 7700 XT | 48 MB |
| RX 7600 XT | 32 MB |
| RX 7600 | 32 MB |
As you can see, the best from the current generation are better than the leaked values. While that may sound odd, it does make sense following reports that AMD likely won’t release high-end RX 8000 GPUs, so we’re looking more around the mid-range level for next-gen.
Not the only leak this week
Earlier this week, we reported on another leak by Kepler_L2 that gave details about RDNA 4 GPUs’ memory bus and memory speed. As per that post, the entry-level GPU will have a 192-bit bus and 19 Gbps memory speed. The ‘mid’ model seems to have a 256-bit bus and 19 Gbps speed. The high-end model will come with a 256-bit bus and a memory speed of 20 Gbps.
In addition to this, one of the RDNA 4 GPUs recently appeared on Geekbench and gave us a glimpse into some technical specifications. The GPU seems to have 28 Compute Units and a maximum frequency of 2101 MHz. The benchmark also mentioned that it has a 16GB VRAM but did not specify if it was GDDR6 or GDDR6X.
In any case, we wouldn’t know the exact specifications and performance until AMD launches the GPUs and we get to review them. It is being speculated that AMD might unveil the 8000 series graphics cards next year at CES 2025.
