Radeon RX 6300M Crosses Swords With GeForce MX450 In Geekbench 5

AMD's Radeon RX 6300M has appeared in a pair of new Geekbench 5 benchmark results with underwhelming performance. Scores in the Vulkan and OpenCL (via Benchleaks) benchmarks showed Nvidia's previous-generation MX450 mobile GPU close to outperforming the Radeon RX 6300M.

AMD's Radeon RX 6300M is the entry-level mobile GPU for its latest RDNA 2 lineup on the spec sheet. The GPU packs just 12 compute units for 768 cores on a cut-down Navi 24 die. Video memory and Infinity Cache sizes are just as neutered, with a maximum supported capacity of just 2GB for the main GDDR6 memory and a measly 8MB of the Infinity Cache.

AMD reduced the clock speeds by quite a substantial rate, with a maximum game frequency of just 1,512 MHz on AMD's reference spec sheet. On the flip side, GPU power consumption is very power efficient at just 25W or lower.

To demonstrate how truly weak the Radeon RX 6300M is, AMD's new Radeon 680M, an integrated graphics chip for Ryzen 6000 and not a discrete GPU, competes directly with the 6300M on several fronts. The Radeon 680M has the exact core count as the Radeon RX 6300M but has a far superior boost frequency of 2.4 GHz. You can make a case for the Radeon RX 6300M with its quicker GDDR6 memory, but the 2GB capacity will severely handicap the Radeon RX 6300M in gaming applications.

An HP Zhan 99 Pro G9 AIO system produced Geekbench 5 results. It was packing an Intel Core i7-12700 (Alder Lake) CPU and 16GB of memory. The Radeon RX 6300M is a strange combination, with it being a mobile GPU that accompanies a desktop chip.

The Geekbench 5 OpenCL results for the Radeon RX 6300M system managed 30,044 points and 24,371 points for the Vulkan benchmark results. These results are pretty poor for any modern GPU. The Radeon RX 6300M can barely outperform Nvidia's Turing-based MX450 entry-level GPU in the OpenCL score, with the MX450 scoring 29,000 points flat. But, the Radeon RX 6300M fails to beat the MX450 in the Vulkan score with a score of 24,688 points for the Nvidia GPU.

Unfortunately, as we've seen in the past, Geekbench 5 isn't the best benchmark for measuring gaming performance. So instead, we need some gaming benchmarks to see how the Radeon RX 6300M measures up to its Nvidia rivals.

    So, this entry level chip does outperform the competition at a very low power budget - as it's supposed to. The entire article tries to destroy it : "almost outperformed by" the mx450, then "almost doesn't outperform" : the mx450 is a chip that doesn't really allow gaming, neither does this one. But at least it's small, sips power, and only uses 4 PCI-e lanes.

    So the smallest siblings of each Familes respective generation are fighting it out.

    It's like watching two little kids flailing their little arms at each other.

    I would say it still looks decent.

    I say first, don't expect magic. These GPUs are all limited by power consumption. There is no point in dumping in more cache, more CUs, more clockspeed etc because its only going to drive up power consumption.

    These GPUs on'y have 15-30W power envelope, so even a GTX3090TI is absolutely useless here. And then, there is thermal too.... Cooling in these laptops are nowhere near decent, mostly even inadequate.

    This is why I said earlier that the performance is pretty decent. You will find many of these GPUs in thin and light laptops weighing less than 1.5KG, so you can imagine the environment these chips and in and the cooling capacity. USers only expect them to be better than the integrated GPUs by Intel/AMD, thats all.

    Lol.... But these 2 little kids are very very important. They go where no adults could. These kids operate in mostly thin and light laptops where there is very limited power and cooling.

    When the full fat RX 6500 XT is bad, cutting more and more out of a bad product is just going to result in a worst product. “Cross sword” with a MX450 in my opinion is not a complement when this is a Turing part that is also superseded by the MX5xx series. And frankly, if the iGPU in Rembrandt APUs are shown to be faster than a MX450 in some of the video reviews I saw online, then it makes you wonder why bother to go with such low end GPUs, while still taking a hit in terms of power consumption.
