It appears that AMD has another budget entry-level NAVI GPU in the works, as spotted in a latest Dell XPS Desktop (8940) PC listing. The new GPU is the NAVI 14 variant, the RX 5300.
AMD released the Radeon RX 5300M mobile variant in November last year, but a desktop version was never released to the market. Dell’s listing does not specify any exact date; but the Radeon RX 5300 is indeed coming. It just remains to be seen whether the graphics card will be an OEM-exclusive SKU, or it will hit the retail shelves as well.
Based on the Radeon RX 5300M’s specs, the new Radeon RX 5300 GPU is presumed to use the same Navi 14 die. So we can expect the GPU to rock 1,408 Stream Processors (SPs).
Back in May 2020, a leaked CompuBench benchmark from late 2019, shared by hardware leaker @Komachi_Ensaka, showed a GPU codenamed as AMD 7340:CF, which was rumored to be AMD’s entry-level Radeon RX 5300 model.
This unconfirmed chip had 3GB of GDDR6 memory, and a maximum boost clock speed of 1,900 MHz and 24 Compute Units (CUs). Based on the current RDNA architecture, the rumored RX 5300 could also have a total of 1,536 Stream Processors (SPs), which means it may give the Radeon RX 5500 XT a run for its money in the budget segment, though this remains to be seen.
If this graphics card is indeed the Radeon RX 5300, it will most likely be Navi 14 silicon GPU that has PCIe 4.0 support, and will probably come with 14Gbps memory complemented with a 96-bit wide memory interface bus, assuming AMD is using the same specifications as the mobile variant. This graphics card will be part of Dell’s post launch plans for the XPS Desktop, alongside the RX 5700 and RX 5700 XT. It might hit the retail shelves as well, assuming this is not an OEM-only SKU.
For context, the Radeon RX 5300M has 14Gbps memory across a 96-bit memory interface. If AMD follows the same recipe, then this new NAVI 14 GPU might pump out a memory bandwidth of up to 168 GBps. Desktop GPUs also have more headroom for a higher thermal power limit, so we expect the RX 5300’s TDP to be higher than 85W (of the RX 5300M chip).
However, the Radeon RX 5300 is an entry-level GPU targeting the budget mainstream market, so the power requirements are not going to be high. A single 6-pin PCIe power connector seems more likely for this GPU.
