It gained intial popularity for it&rsquo;s use in video processing or gaming and more recently for training large language models.</p> <p>But why are GPUs so fast and are they always faster than CPUs? The answer lies in the architecture. A GPU is designed to perform single instruction over multiple data acronymed SIMD. A CPU usually contains Control Unit, Arithmatic Logic Unit, registers etc. More recently CPU have multiple cores, each cpu works like a mini cpu with it&rsquo;s own CU and ALU. If a CPU has 4 cores, it can operate 4 instruction truly in parallel. GPU are different, they can 1000s of threads in parallel.</p> https://www.rkoush.com/posts/tpu/ Fri, 01 May 2026 00:00:00 +0000 https://www.rkoush.com/posts/tpu/ <h3 id="tensor-processing-units-tpu">Tensor processing Units (TPU)</h3>
