Radeon RX 7600 final specifications leaked, 165W TDP & 2625 MHz boost

Unofficial sources reveal key details about the AMD Radeon RX 7600 graphics card. This latest offering, founded on the RDNA3 architecture, suggests higher power needs than its predecessor.

The RX 7600 boasts a Typical Board Power (TBP) of 165W, necessitating a minimum 550W power supply - a 33W increase from the RX 6600 GPU, which is built on the RDNA2 framework. AMD has included a comparative power consumption chart in their reviewer's guide to illustrate this difference.

Several other details have emerged shortly before the product's launch, confirming the complete specifications including clock speeds and memory configuration. Though not entirely new - as AMD has already released similar data for its mobile series - these specifications are specific to the desktop version. The card is expected to have a game clock of 2250 MHz and a boost clock of 2625 MHz. These specifications are in line with previous leaks, although the boost clock of the reference model is reported to be slightly lower. The card will incorporate a full configuration of 32 Compute Units and 2048 Stream Processors for the Navi 33 GPU.

The leaked information also indicates that the RX 7600 will feature quicker memory than the RX 6600. It will house 18 Gbps GDDR6 modules, offering a maximum bandwidth of 288 GB/s. AMD's data suggests an effective bandwidth of 477 GB/s when taking into account the Infinity Cache, a modest improvement over the RX 6600's 413 GB/s. Despite the increase in memory speed, the memory bus remains at 128 bits. Like its predecessor, the RDNA3 model will maintain an 8-lane limit on its interface.

The Radeon RX 7600's official launch is anticipated on May 25th. The RX 7600's core GPU, while based on the advanced RDNA3 graphics architecture, continues to utilize the 6 nm (DUV) silicon fabrication process from the prior "Navi 24" GPU. The silicon transistor count is approximately 13.3 billion, around 2 billion more than the 7 nm "Navi 23" in the RX 6600 series, while the die-size is constant at 204 mm². The GPU maintains a PCI-Express 4.0 x8 host interface and a 128-bit GDDR6 memory interface.

The RX 7600 incorporates 32 RDNA3 compute units (CU), translating to 2,048 stream processors. It shares the dual-issue instruction rate characteristic with the RX 7900 series. Additionally, it boasts 32 Ray Accelerators and 64 AI Accelerators. The GPU has 128 TMUs and 64 ROPs, in addition to 32 MB of second-generation Infinity Cache memory. The 8 GB of GDDR6 memory operates at 18 Gbps, enabling a memory bandwidth of 288 GB/s across the 128-bit memory bus. According to AMD, the effective bandwidth is further enhanced when combined with the on-die cache.
