Are stream processors the same as Cuda cores?

Stream Processors and CUDA Cores are branded names for the same thing: a parallel processor and the set of rules for its operation. In practice, the two are fundamentally different because AMD and NVIDIA each use their own unique architecture.

How many cores is a CUDA core?

The Nvidia GTX 960 has 1024 CUDA cores, while the GTX 970 has 1664 CUDA cores….How CUDA cores affect the performance?

	Nvidia Geforce GTX 980 Ti	GTX Geforce GTX 1080
No. of Transistors	8,100,000,000	7,200,000,000
No. of CUDA cores	2816	2560
No. of Transistors/Core	2,876,420	2,812,500
Clock speed	1500 MHz	2000 MHz

What is a GPU stream processor?

2 Streaming Processor. A fundamental unit of GPU is a streaming processor (SP). This provides the capability to fetch a single instruction from memory and carry it out on different data sets in parallel. Each GPU contains tens to hundreds of SPs in a single piece of hardware.

How many streams does CUDA have?

There is no realistic limit to the number of streams you can create (at least 1000’s). However, there’s a limit to the number of streams you can use effectively to achieve concurrency. In Fermi, the architecture supports 16-way concurrent kernel launches, but there is only a single connection from the host to the GPU.

What is CUDA default stream?

Before CUDA 7, the default stream is a special stream which implicitly synchronizes with all other streams on the device. CUDA 7 introduces a ton of powerful new functionality, including a new option to use an independent default stream for every host thread, which avoids the serialization of the legacy default stream.

What is a stream CUDA?

A stream in CUDA is a sequence of operations that execute on the device in the order in which they are issued by the host code. While operations within a stream are guaranteed to execute in the prescribed order, operations in different streams can be interleaved and, when possible, they can even run concurrently.
