GeForce GTX 645 (OEM) Game Requirement Analysis

Overview
GeForce GTX 645 is an OEM only, Fast-Middle-Class Graphics Card based on the First Revision of the Kepler Architecture.


Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.


GPU
It equips a GPU codenamed Kepler GK106 which has 3 Stream Multiprocessors activated and thus offers 576 Shader Processing Units, 48 TMUs and 16 ROPs. The Central Unit is Initially Clocked at 823 and goes up to 888MHz, in Turbo Mode.


Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1000MHz.


Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies.


Power Consumption
With a rated board TDP of 65W, it requires at least a 450W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.


Performance
Gaming Benchmarks put its Performance on average with GeForce GTX 650.


System Suggestions
We recommend a Modest Processor (Intel Core i3) and 8GB of RAM for a system with GeForce GTX 645.
