The difference is in the real-time scheduling requirements that come with a GUI. Very minor delays in GUI rendering have very perceptible impact on the snappiness of a UI. Server workloads (DB, HTTPD or whatever) have less stringent real-time requirements. Throughput ends up mattering more as long as the latency is in a reasonable range.
