The portal HD Tecnologia announced the detailed characteristics of the upcoming Radeon RX 7600 graphics card based on the RDNA 3 architecture, which AMD will present later this month. There were no surprises. Perhaps most interestingly, the Navi 33 GPU is made on the same 6nm process as the previous generation Navi 24.
The Navi 33 chip contains 13.3 billion transistors, which is about 2 billion more than the Navi 23, which is based on the Radeon RX 6600’s 7nm process technology. At the same time, the Navi 33 GPU itself is smaller than its predecessor, measuring 204 mm2. The chip only supports 8 PCIe 4.0 lanes and a 128-bit GDDR6 memory bus. The power consumption of the Radeon RX 7600 is 165W, which is 30W higher than the Radeon RX 6600.
The Radeon RX 7600 GPU features 32 RDNA 3 execution units with 2048 stream processors with support for two simultaneous FP32 operations, like the older Radeon RX 7900 series models. The chip also features 32 ray tracing accelerators, 64 AI acceleration units and 128 texture units, 64 ROP and 32 MB second generation Infinity Cache. The gaming frequency of the GPU is 2250 MHz, in boost mode it increases to 2625 MHz.
The Radeon RX 7600 graphics card received 8 GB of GDDR6 memory with a speed of 18 Gbps per pin and a bandwidth of up to 288 GB/s. According to AMD, the “effective bandwidth” of the memory reaches 476.9 GB/s thanks to Infinity Cache.
AMD recommends using a 550W PSU in Radeon RX 7600 PCs. For comparison, the previous generation Radeon RX 6600 model required a 450W power supply. The manufacturer considers the Radeon RX 7600 a direct successor to the regular RX 6600 model and not the RX 6600 XT or RX 6650 XT.
