Dell EMC Associate – PowerEdge Server Specialist — Question 21

How does GPGPU compare to CPU in a Dell EMC PowerEdge server?

Answer options

• A. GPGPU is somewhat limited on running instructions concurrently, and CPU simultaneously executes a single instruction stream on multiple data elements
• B. GPGPU is only used for video output in servers, and CPU is used for computational power
• C. GPGPU has no memory on its own and fully relies on RAM, but CPU memory resource is reduced by 20GB per installed GPGPU
• D. GPGPU simultaneously executes a single instruction stream on multiple data elements, and CPU is somewhat limited on running instructions concurrently

Correct answer: D

Explanation

The correct answer is D, as it accurately describes the GPGPU's capability to handle parallel processing effectively while the CPU is restricted in concurrent instruction execution. Option A is incorrect because it misrepresents the GPGPU's strengths in parallel execution. Option B is false because GPGPU is not limited to video output; it is designed for general-purpose computing tasks. Option C is misleading as it implies a direct memory trade-off that is not typically how GPGPU and CPU memory management works.
