Comparison of Nvidia Quadro RTX 3000 and A3000
Hello everyone, I'm considering purchasing either a Dell Precision 7750 or 7760 paired with either the Quadro RTX 3000 or A3000. I've studied these models thoroughly; while the A3000 offers some impressive features, I'm concerned about its 600MHz clock speed. I'm unsure if adding more CUDA cores will make up for that limitation. In terms of performance, I'm leaning toward the RTX 3000 but worry about relying on tensor cores in the A3000. I want a reliable choice for my architectural work and rendering tasks, as this clock speed is affecting my confidence. I really value your advice and suggestions. Thank you.
Both RTX 3000 and A3000 start at a base frequency of 600MHz, with the boost clock varying by just 15MHz (1215MHz versus 1230MHz). The main distinction lies in the number of shaders: RTX 3000 features 2304 shaders, while A3000 has 4096 more powerful ones. RTX 3000 is Turing and includes 288 tensor cores, whereas A3000 is Ada and has 128 tensor cores, which are up to four times faster.
I saw a comparison of these two graphics cards, both with 6GB of memory. They state the RTX 3000 has a core clock of 945mhz and the A3000 has 600mhz, even though the A3000 has more cores and better overall specs. Could this core clock speed actually cause slow performance when running heavy software for rendering and CAD? In my opinion, is the 600mhz more than sufficient for normal rendering tasks, or is there something missing I’m not seeing?
I believe the base clock has little impact since no work is performed at that level unless specialized software is used to secure GPU clocks and stop boost under heavy use. In a laptop, the 70w A3000 tends to maintain higher clocks compared to an 80w RTX 3000 mainly due to thermal considerations. It seems the RTX 3000 also offers a power-saving 60w Max-Q version that runs at 600MHz. The 80w model features a 945MHz base clock and can reach up to 1380MHz. The A3000 is over 25% quicker than the Max-Q model but only slightly faster than the 80w RTX 3000, excluding tensor performance differences. Both 600MHz and 945MHz clocks are similar to the speeds of desktop Kepler cards from over a decade ago—the first generation of Nvidia with boost clocks. It’s logical to opt for a lower idle clock in a laptop to reduce fan noise during light use, whereas modern laptops often shut down the GPU and shift tasks to the CPU when idle. Technically, a 600MHz clock versus a 945MHz one doesn’t matter much because the GPU only starts at its default speed when powered on.
