This is the desktop system we used for comparisonĬPU: AMD Ryzen 9 3900X (12-core, up to 4.6GHz) That means the processor isn't fast enough to keep up with the graphics card, especially in situations that tax both components. For instance, in our review for the laptop we used for testing, we found that the processor was able to score 605 points in Cinebench R15, compared to the 1,463 scored by the Intel Core i7-9700K. So right off the bat, there's a lot less bandwidth the GPU can harness, but then you also have to take into consideration that the processor is orders of magnitude slower than a desktop chip.
External graphics card for desktop pcie slot full#
You see, typically when you connect one of the best graphics cards to a motherboard you're able to use the full 16 PCIe lanes for the GPU - Thunderbolt 3, as magical as it is, is limited to just two. Especially when you take high-performance graphics into consideration, there's only so much an external graphics card can do. Pretty much no matter which graphics card they slotted in, they'd get much better gaming performance.īut here's the issue. This external graphics box would connect to the laptop through Thunderbolt 3 – still the only connection with enough throughput to power external graphics – and rely on the user to slot in the graphics card of their choosing. Instead, Razer urged users to pick up the Razer Core V1 alongside the Razer Blade Stealth in order to boost gaming performance when at home.
