Rumor: It seems strange that when it comes to finding graphics cards that are out of the market and their prices are very high, rumors of new models are undoubtedly very expensive. After talking about the RTX 3090 Super, we now hear that AMD is working on a Radeon RX 6900 XTX to consume the current Nvidia flagship.
News of the Radeon RX 6900 XTX comes from Twitter user CyberPunkCat (via Tom's Hardware), who claims to be an AMD chip showing an unpublished card. As 3DCenter, which recently revealed a new graphics card price hike, points out, the chipset's specs match exactly the Radeon RX 6900 XT Liquid Cooled (LC) available only to manufacturers - this may be a relevant older chip. to the LC card, so it consumes a lot of salt.
But, if this chip is all-new for the Radeon RX 6900 XTX, what can we expect to see? The current version of the RX 6900 XT has two variants: one equipped with a Navi 21 XTX GPU and the other with a Navi 21 XTXH version. The latter is used in high-end cards such as the ASRock Radeon RX 6900 XT OC Formula.
Most likely every RX 6900 XTX uses a Navi 21 XTXH GPU with faster memory and speed. According to the chip, it offers up to 24.93 TFLOP with FP32 performance, which puts it ahead of the 23.04 TFLOPS RX 6900 XT. The frequency of the new card is also expected to be 2.435 MHz, while the frequency of the vanilla version is 2,250 MHz. This gives the RX 6900 XTX an 8% increase in clock speed and performance. Elsewhere, memory increases from 16 Gbps to 18 Gbps. The 16GB GDDR6 memory remains unchanged, despite the theoretical bandwidth increase to 576GB/s, which is 13% faster than the RX 6900 XT. We may also see an increase in TDP from 300W to 350W.
A few days ago we heard rumors about a 450W RTX 3090 Super with 21Gbps VRAM. Will it compete with the Radeon RX 6900 XTX? Assuming they are real, a better question might be whether one can find/buy one of these animals.
