Intel's game-only A380 graphics card is already on the market, the price was suggested to be 1030 yuan, but the actual price reached 1299 yuan, with AMD's RX 6400, NVIDIA's GTX 1630, a thousand yuan level of unique display market competition.
However, the A380 graphics card still has many small problems, especially the compatibility. The previous official Intel document pointed out that it needs to be matched with Intel 10 generation core platform and above, and didn't even mention the support of AMD platform, which caused A bit of dissatisfaction.
The problem is not that Intel is deliberately limiting the AMD platform, but rather the motherboard's rBAR support. This is the SAM smart memory access technology that AMD has been pushing, which, when turned on, allows the CPU to access the entire frame buffer instead of the fixed 256MB data, improving game performance.
How much impact does rBAR have? According to a previous test conducted by German Computerbase website, the performance gap between AMD platform without rBAR and with rBAR enabled is as much as 34%. With rBAR enabled, the performance of Ryzen 5 5600X with Zen3 architecture can catch up with Core I5-12500.
For example, DOTA2 games will crash on AMD platforms with rBAR disabled. Intel graphics executive Ryan Shrout has confirmed that the A380 should support rBAR with AMD platforms. Intel hasn't had time to verify it, and it expects that any graphics card, including future higher-end ones, should work properly.
