In terms of overall gaming performance, the graphical capabilities of the Intel G1 900MHz are significantly better than the Nvidia GeForce GT 445M v2.

The GT 445M has a 270 MHz higher core clock speed but 8 fewer Texture Mapping Units than the G1 900MHz. The lower TMU count doesn't matter, though, as altogether the GT 445M manages to provide 4.1 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 13 more Render Output Units than the G1 900MHz. This results in the GT 445M providing 8.2 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 G1 900MHz was released over three years more recently than the GT 445M, and so the G1 900MHz 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 1024 MB video memory, but the G1 900MHz does not have an entry, so the two GPUs cannot be reliably compared in this area.

The G1 900MHz has 256 Shader Processing Units and the GeForce GT 445M v2 has 144. However, the actual shader performance of the G1 900MHz is 230 and the actual shader performance of the GT 445M is 164. The G1 900MHz having 66 better shader performance is not particularly notable, as altogether the GT 445M performs better when taking into account other relevant data.

The G1 900MHz transistor size technology is 30 nm (nanometers) smaller than the GT 445M. This means that the G1 900MHz is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M.

The G1 900MHz requires 28 Watts to run and the GeForce GT 445M v2 requires 35 Watts. The GT 445M requires 7 Watts more than the G1 900MHz 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 G1 900MHz.

GPU Mini Review

Mini ReviewOverview
Intel Iris Plus Graphics G4 900MHz are integrated graphics in some of Intel's Ice Lake mobile processors. It can be found in Intel Core i3-1000G1 & Intel Core i3-1005G1

The Ice Lake architecture succeeds the Kaby lake architecture and aims for increased CPU and graphics performance.
New Features
These Gen 11 graphics solutions include the new Variable Rate Shading (VRS) support. This lets shading time for object shading in game to be allocated more accurately by the game's developers. So for example, a graphics depicting an object that cannot easily be seen can be marked as not needing such high performance and visual accuracy and thus save processing power. GPU
The central unit initially runs at 300MHz and goes up to 900MHz, in turbo mode.

Because Performance depends heavily on the Memory Bandwidth, it may vary from System to System.
Best case scenario, expect Intel Iris Plus Graphics G1 900MHz performance to be not as powerful as the older Iris Plus 640 onboard solution, which will reduce potential AAA gaming chances moving forward. We dont recommend this onboard solution for modern gaming.
GeForce GT 445M v2 is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Fermi 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.

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.

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.

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.

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.
