The AMD RX 7900 XT and RX 7900 XTX launches this past December were exciting. AMDs latest generation of cards showed that the giant cards that Nvidia had recently launched weren’t the only option with the upcoming generation and they had impressive performance as well. Sadly I didn’t get to see Sapphire's take on the new generation of cards but that changes today. They sent over the Sapphire RX 7900 XT Pulse and today I’m going to dive in and see what it has going on and then put it through our test suite to see how it performs. I’m especially curious to see how it compares to AMDs reference design as well as the RTX 4070 Ti and we can take a second look now and see how the 7900 XT fits in the market now that things have had time to settle down post-launch. So let’s dive in!

Boost Clock is the maximum frequency achievable on the GPU running bursty workload. Boost clock achievability, frequency, and sustainabilty will vary based on several factors, including but not limited to: thermal conditions and variation in application and workloads.

 

Game Clock is the expected GPU clock when running typical gaming applications, set to typical TGP(Total Graphics Power). Actual individual game clock results may vary.

Before getting into testing I did also run GPUz to double-check that our clock speeds match up with the specifications. The Sapphire 7900 XT Pulse is listed with a boost clock of up to 2450 MHz and a game clock of up to 2075 MHz and GPUz has the game clock spot on but the boost clock was listed at 2449 MHz which is 1 MHz off, not a big deal or anything and right where it needs to be. For comparison, the reference 7900 XT had a game clock of 2000 MHz and a boost clock of up to 2400 MHz so Sapphire has given the Pulse a bump across the board but not a huge overclock by any means. Beyond that GPUz also documents the driver used for testing which is the latest AMD driver and the BIOS version for reference in the future as well.
