AMD Radeon RX 7700 XT vs AMD Radeon RX 7600M vs AMD Radeon RX 7600M XT

AMD Radeon RX 7700 XT

The AMD Radeon RX 7700 XT is a mid-range desktop GPU and is primarily designed for gaming in 1,440p. This makes the AMD Radeon RX 7700 XT the smallest offshoot in the 1,440p gaming segment, placing it directly behind the AMD Radeon RX 7800 XT and the AMD Radeon RX 7900 GRE. The graphics chip is manufactured using the 5 nm process at TSMC. The chiplet design is also used in the AMD Radeon RX 7700 XT, although only three MCDs are active here. With 12 GB of VRAM, the AMD Radeon RX 7700 XT has just as much as the AMD Radeon RX 6700 XT, which is its direct predecessor.

Features

RDNA 3 continues to serve as the basis for the graphics chip called Navi 32. The already established features such as SAM (Smart Access Memory) and the Infinity Cache are also available in the new mid-range model aka Radeon RX 7700 XT. Compared to the AMD Radeon RX 6700 XT the ray tracing part has been revised and AI support has been implemented on the hardware side. The media engine has been updated and videos can be decoded/encoded with a resolution of up to 8K. The modern DisplayPort 2.1 connection is also available on the AMD Radeon RX 7700 XT. AMD's answer to DLSS is FSR 2.0 and offers a significant increase in performance in games with the upscaling option. With FSR 3, there will be another feature in the near future which, like DLSS 3.0, promises even better frame rates thanks to frame generation.

Performance

The performance of the AMD Radeon RX 7700 XT in games without ray tracing is well ahead of an Nvidia GeForce RTX 4060 Ti. The Nvidia GeForce RTX 4070 is out of reach for the AMD Radeon RX 7700 XT. In the in-house duel, the performance of the AMD Radeon RX 7700 XT can be compared with an AMD Radeon RX 6800 can be compared.

Power consumption

The power consumption of the AMD Radeon RX 7700 XT is estimated by the manufacturer at 245 watts (TBP) and is therefore only marginally more economical than an AMD Radeon RX 6800 (250 watts). Compared to the Nvidia GeForce RTX 4070 the AMD Radeon RX 7500 XT requires 45 watts more.

AMD Radeon RX 7600M

The AMD Radeon RX 7600M is a mobile upper mid-range graphics card based on the Navi 33 chip (RDNA 3 architecture) manufactured in 6nm. It features 1,792 cores (28 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The specified game clock speed is 2070 MHz (most likely at 90 W TGP). 

The performance should be similar to the old Radeon RX 6650M XT (28 CUs RDNA 2, higher clock speed) and therefore best suited for 1080p gaming. Although the Raytracing performance did increase for RDNA 3, the GeForce GPUs are still faster in this regard.

The Navi 33 chip is manufactured at TSMC in the current 6nm process (versus 4nm of Nvidia RTX 4000 series). The power consumption (TGP) is specified at 50 to 90 Watt.

AMD Radeon RX 7600M XT

The AMD Radeon RX 7600M XT is a mobile upper mid-range graphics card based on the Navi 33 chip (RDNA 3 architecture) manufactured in 6nm. It features 2,048 cores (32 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The specified game clock speed is 2300 MHz (most likely at 120 W TGP). 

AMD compares the performance to the RTX 3060 desktop GPU and claims significantly faster frame rates in a couple of games (without Raytracing). Although the Raytracing performance did increase for RDNA 3, the GeForce GPUs are still faster in this regard.

The Navi 33 chip is manufactured at TSMC in the current 6nm process (versus 4nm of Nvidia RTX 4000 series). The power consumption (TGP) is specified at 75 to 120 Watt.
