RADEON RX 9070 GRE: NAVI-48 GPU Review, 158 Reviews, Starts in China from 500 Euros
The rumors are right: AMD is launching the Radeon RX 9070 GRE, another graphics card with RDNA-4 architecture. It has already officially launched in China. The 48 compute units speak for a heavily circumscribed 48 GPU. 12 GB of memory is also a step down from the RX 9070 (XT).
RX 9070 GRE Starts in China Today
The Radeon RX 9070 GRE was already mentioned in the rumor mill earlier this month, and shortly before Easter, there were specific hints of its key specifications. These are officially confirmed today, as AMD China now lists all specifications and pre-orders in that country.
Navi 48 heavily cropped
As previously specced, the Radeon RX 9070 GRE, as well as the Radeon RX 9070 and RX 9070 XT, use the NAVI 48 graphics chip, which reveals the same number of 53.9 billion transistors. However, significantly fewer compute units are active on the RX 9070 GRE. The number of compute units decreases from 64 on the RX 9070 XT and 56 on the RX 9070 to just 48 on the RX 9070 GRE. Compared to the RX 9070 XT, it has 25% less CUS and about 14% less Cu than the RX 9070. The number of Fp32-Alus coupled by it accordingly drops to 3,072.

But that’s not the only clear cut. The memory interface has also been shortened by 25%: 192-bit instead of 256-bit. Similarly, the storage capacity of only 12 GB instead of 16 GB is lower for the faster sister models. In addition, the memory chips with 18 Gbps are still 10% slower instead of 20 Gbps.

The bottom line is not only 25% less memory, but its throughput has also been reduced to just 432 GB/s instead of the 645 GB/s of its larger siblings. The RX 9070 GRE can only beat the RX 9070’s game clock: 2220 MHz is over 150 MHz higher and 2790 MHz is even 270 MHz higher than the RX 9070, but the RX 9070 XT is even faster.
Gap filling
The performance potential of the new RX 9070 GRE therefore differs considerably from that of the other NAVI 48 models. But that’s exactly what’s needed, as the GRE version is intended to fill the gap in the upcoming RX 9060 series. The latter relies on the much smaller NAVI 44 GPU. Since AMD no longer has the chip, only the powerful NAVI 48 remains as a gap filler.
Currently only in China
The Radeon RX 9070 GRE is only available in China. Pre-orders are available at prices starting at around 4,200 yuan. At the current exchange rate, that’s around $575,500.
It remains to be seen when and at what prices the market launch will take place in other regions of the world. The predecessor, the RX 7900 GRE, was initially released only in China and was later introduced in the Western world. The newcomer will launch in China on May 8, according to Benchlife.
Only 6% faster than the 7900 GRE
A big performance leap over the RX 7900 GRE is not to be expected. AMD even reports an average 6% increase at 1440p and “Ultra” settings in 30 selected games.
However, it’s also worth keeping in mind that AMD hasn’t included a high-end chip in this generation, and the RX-9070 series is more likely to be considered the successor to the RX-7800/7700 series.
