Evidently, not all reference Radeon RX 6700 XT graphics cards will arrive with the same clock speeds — Biostar (via VideoCardz (opens in new tab)) has listed a reference design that flaunts a small factory overclock.
Biostar refers to the graphics card as "VA67T6TEL9 Ver. RX6700XT M," although it's uncertain if that's the actual model name or the part number. The manufacturer used a render of AMD's reference Radeon RX 6700 XT, but the packaging itself has the "Extreme Gaming" label. The last bit may allude to the fact that Biostar's version is clocked higher than the usual reference edition.
AMD lists the Radeon RX 6700 XT with a 2,321 MHz base clock and game and boost clocks up to 2,424 MHz and 2,581 MHz, respectively. The Biostar Radeon RX 6700 XT features slightly higher clock speeds across the board. The graphics card arrives with a 2,330 MHz base clock, and game and boost clocks that scale to 2,433 MHz and 2,615 MHz, respectively. The increase in base and game clocks is negligible, while the boost clock showed a 1.3% uplift.
In case you missed AMD's announcement, the Radeon RX 6700 XT debuts with the Navi 22 silicon that's fresh out of TSMC's 7nm cooking oven. Navi 22 ushers in 40 Compute Units (CUs) for a grand total of 2,560 Streaming Processors (SPs). The graphics card also packs 40 ray accelerators. The Radeon RX 6700 XT offers 12GB of 16 Gbps GDDR6 memory that runs across a 192-bit memory interface to supply a memory bandwidth up to 384 GBps. The number might look disillusioning, but let's not forget that AMD offsets the memory with 96MB of Infinity Cache.
The Radeon RX 6700 XT will hit the stores on March 18 for $479. The RDNA 2 graphics card will take on the GeForce RTX 3070, which starts at $499. With the graphics card shortage still transpiring, it might not be a battle of who is the fastest, but rather which card is readily available for purchase. AMD has promised to have substantially more Radeon RX 6700 XT stock at launch, so let's hope the chipmaker delivers.
I own a Vega 56 and I think I saw it has more stream processors than the 6700XT, so, not sure if worth the upgrade.
Those RDNA2 stream processors used in the new RX 6xxx series are much faster and more efficient than the ones used in Vega. Since its targeting the 3070, lets use that as an example, in the review below you have the Vega 56 getting 46 FPS on Cyberpunk 2077 at 1080p Ultra, while the RTX 3070 gets 91. The story is similar throughout that entire review, with the 3070 being 50 - 100% faster depending on the game and settings. Since the RX 6700 is aiming for that level of performance, you can expect it to maintain roughly the same lead over your current Vega 56. If you can find one at a decent price, it may be worth the upgrade. That being said, its not like your Vega 56 cant still game, it just cant game at as high of a level as the newer cards.
