In terms of overall gaming performance, the graphical capabilities of the Intel Iris Graphics 540 Mobile are very slightly better than the Nvidia GeForce GT 445M v2.

The GT 445M has a 270 MHz higher core clock speed and 16 more Texture Mapping Units than the Graphics 540. This results in the GT 445M providing 11.3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 445M has a 270 MHz higher core clock speed and 14 more Render Output Units than the Graphics 540. This results in the GT 445M providing 8.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Graphics 540 was released over three years more recently than the GT 445M, and so the Graphics 540 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GT 445M when running the latest games.

The GT 445M has 960 MB more video memory than the Graphics 540, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 445M also has superior memory performance overall.

The GT 445M has 5.9 GB/sec greater memory bandwidth than the Graphics 540, which means that the memory performance of the GT 445M is marginally better than the Graphics 540.

The Iris Graphics 540 Mobile has 48 Shader Processing Units and the GeForce GT 445M v2 has 144. However, the actual shader performance of the Graphics 540 is 403 and the actual shader performance of the GT 445M is 164. The Graphics 540 having 239 better shader performance is not particularly notable, as altogether the GT 445M performs better when taking into account other relevant data.

The Graphics 540 transistor size technology is 26 nm (nanometers) smaller than the GT 445M. This means that the Graphics 540 is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M. While they exhibit similar graphical performance, the Graphics 540 should consume less power than the GT 445M.

The Iris Graphics 540 Mobile requires 15 Watts to run and the GeForce GT 445M v2 requires 35 Watts. The GT 445M requires 20 Watts more than the Graphics 540 to run. The difference is not significant enough for the GT 445M to have a noticeably larger impact on your yearly electricity bills than the Graphics 540.

GPU Mini Review

Mini ReviewOverview
Intel Iris Graphics 540 Mobile are Integrated Graphics in some of Intel's Skylake Mobile Processors.

Architecture
The Skylake Architecture succeeds the Broadwell Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. It includes support for DirectX 12.1, OpenCL 2.0 and OpenGL 4.4, as well as DDR4 Memory Support.
The GPU Codenamed GT3-U offers 48 Shader Processing Units, 8 TMUs and 2 ROPs.

GPU
The Central Unit Initially Runs at 350MHz and goes up to 1050MHz, in Turbo Mode.

Memory: Speed
The Operating Memory Clock depends at which speed the System's RAM is running and which Memory Type is installed and is ultimately limited by the highest operating speed that the Processor supports. In this case, it is 933MHz for DDR3 and 1067MHz for DDR4.
Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface.
An addition to the Iris Graphics is the access to a L4 Cache of 64MB eDRAM which further increases the Memory Performance.

Memory: Frame Buffer
The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 1.7GB.

Performance
Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System.
Best Case Scenario, expect Performance Identical to a dedicated GeForce 830M.

System Suggestions
Intel Iris Graphics 540 Mobile is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
Overview
GeForce GT 445M v2 is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF106-N11E-GE-A1 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 570MHz.

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 625MHz.

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

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its performance almost on level with the desktop GeForce GT 450 v4.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 445M v2.
