To appropriate NVIDIA’s GeForce RTX 3080 Ti dispatch, AMD had worked with its accomplices to deliver an invigorated Radeon RX 6900 XT dependent on a chic new ASIC inside named “XTXH.” This is basically the most elevated canister of the “Navi 21” silicon that permits 10% higher clock speeds over the standard RX 6900 XT. Our testing of one such card, the ASRock RX 6900 XT OC Formula, showed that the XTXH can exchange blows with the RTX 3090, making it serious with the RTX 3080 Ti. Curiously, there appeared to come up short on a reference configuration “made by AMD” card dependent on this silicon. Ends up, AMD had different plans. This card was before accepted to be the “Radeon RX 6900 XTX,” when it was first spilled in April, however ends up, that AMD is permitting accomplices to just consider this the RX 6900 XT.
The reference configuration card utilizes a fluid cooled plan. The actual card is two openings thick, and about the size of the reference Radeon RX 6800, yet two coolant tubes rise out of its top, which head to a 120 mm x 120 mm radiator. This is an absolutely fluid cooled card, with no auxiliary air-based cooling, similar to the ASUS ROG Strix LC RX 6900 XT. The lone wellsprings of clamor are the AIO siphon block, and the single included 120 mm fan. Other than 10% higher GPU timekeepers, the reference configuration card has a secret weapon that specially craft XTXH cards need—quicker memory.
A posting of a Sapphire-marked reference fluid cooled card on Brazilian online store Kabum claims that the card accompanies a memory clock speed of 18 Gbps GDDR6. Samsung has been mass-creating 18 Gbps-appraised GDDR6 memory chips (which are not GDDR6X), since 2018, so all things considered, AMD tied down itself some volume to ship off its reference-plan OEM, PC Partner. At 18 Gbps, the memory transfer speed shoots up to 576 GB/s, from 512 GB/s on the RX 6900 XT.
The card’s motor lift recurrence is recorded as 2435 MHz, which is in the class of other XTXH cards, so dislike the quicker memory is making up for lower motor timekeepers. What’s fascinating, however is that the photos uncover that the card manages with only two 8-pin PCIe power connectors—an arrangement appraised for 375 W—while each specially craft XTXH card utilizes a triple 8-pin design evaluated for 525 W. Kabum claims the card will deliver from 30th June, 2021.
