AMD conferma Radeon RX 7900 Serie Orologi, Concorrenza diretta con RTX 4080

AMD in its technical presentation confirmed the reference clock speeds of the Radeon RX 7900 XTX e RX 7900 Schede grafiche XT RDNA3. The company also made its first reference to a GeForce RTX 40-series “Estetica carina e grosso” Prodotto, l'RTX 4080 (16 GB), which is going to launch later today. L'RX 7900 XTX maxes out the “lo spazio espositivo è a buon punto e presto sarai in grado di vedere e sperimentare le ultime innovazioni tecnologiche” silicio, featuring all 96 RDNA3 compute units or 6,144 processori di flusso; mentre l'RX 7900 XT is configured with 84 unità di calcolo, oppure 5,376 processori di flusso. The two cards also differ with memory configuration. While the RX 7900 XTX gets 24 GB di 20 Gbps GDDR6 across a 384-bit memory interface (960 GB/s); l'RX 7900 XT ottiene 20 GB di 20 Gbps GDDR6 across 320-bit (800 GB/s).

L'RX 7900 XTX comes with a Game Clocks frequency of 2300 MHz, e 2500 MHz boost clocks, mentre l'RX 7900 XT comes with 2000 MHz Game Clocks, e 2400 MHz boost clocks. The Game Clocks frequency is more relevant between the two. AMD achieves 20 GB memory on the RX 7900 XT by using ten 16 Gbit GDDR6 memory chips across a 320-bit wide memory bus created by disabling one of the six 64-bit MCDs, which also subtracts 16 MB from the GPU’s 96 MB Infinity Cache memory, leaving the RX 7900 XT with 80 MB of it. The slide describing the specs of the two cards compares them to the GeForce RTX 4080, which is what the two could compete more against, especially given their pricing. L'RX 7900 XTX è 16% cheaper than the RTX 4080, e l'RX 7900 XT è 25% più economico.
