Asus ROG Strix RX 6650 XT OC Edition: Emphasis on top cooling

If quiet cooling is most important to your card, you should sharpen this model. Thanks to the combination of a not very voracious base and very powerful cooling, Asus produced an exceptionally quiet card with a performance that is sufficient even with a reserve at the still most used resolution.

Two weeks ago, AMD expanded its existing card offering with Radeon RX 6650 XTRadeon RX 6750 XT a Radeon RX 6950 XT.

A new, most powerful model is built on each of the three graphics chips used in the RX 6000 Series Radeons – the Navi 23, Navi 22 and Navi 21. All models received faster memories and higher beats of the graphics chip (and with them the power limit moved higher).

The top of the range is the Radeon RX 6950 XT built on the Navi 21 chip, for which AMD increased the power limit most significantly from the conservative 300 to 335 W and thus the stated chip of the chip with a boost from 2250 to 2310 MHz. The memories increased from 16 to 18 Gb / s.

The RX 6750 XT was also equipped with faster memories with 18 Gb / s instead of the original ones with 16 Gb / s, the power limit is raised from 230 to 250 W and the beat with a boost from 2581 to 2600 MHz.

Finally, the RX 6650 XT tested today received memory instead of 16 Gb / s chips at 17.5 Gb / s, the card’s power limit is shifted from 160 to 180 W and the paper clock of the chip with boost increased from 2589 to 2635 MHz.

The Radeon RX 6950 XT and RX 6750 XT should be sold in parallel with older models, the Radeon RX 6650 XT should gradually replace the Radeon RX 6600 XT.

Today we take a look at another of the top RX 6650 XT models – the ROG Strix RX 6650 XT OC Edition from Asus.

We will start with a classic cover on which the manufacturer has highlighted the most important features of the card – a heatsink with a pair of corporate Axial-tech fans, high-end capacitors, coils and mosfets and machine components, a new cover with metal accents and backlighting with addressable RGB LEDs. Armour Crate’s corporate software to synchronize with other components and support GPU Tweak for card overclocking and monitoring.

In addition to the usual manuals, you will find at least cable ties in the accessories.

GPU-Z reveals a slight increase in factory beats with a boost from 2635 to 2694 MHz and the fact that the card, like the RX 6600 XT bus cut to half width 8 ×, which does not matter for a card with similar performance on PCIe 4.0, but for PCIe 3.0 it for powerful processors, it can sometimes mean units of percent power down.

The card has two BIOSes, but you can recognize it in the diagnostic utilities, but basically only in the BIOS versions, otherwise the parameters such as clock cycles or power limit do not differ. The only difference is in the setting of the curves for fan control and radiator output, but you won’t just read that from GPU-Z. Due to the large reserve of the heatsink, the performance is practically the same, so I tested with a quieter BIOS Quiet (right)
