In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are marginally better than the Intel HD i7 3770S.

The GeForce GT 620 has a 50 MHz higher core clock speed and 12 more Texture Mapping Units than the HD i7 3770S. This results in the GeForce GT 620 providing 8.6 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 GeForce GT 620 has a 50 MHz higher core clock speed than the HD i7 3770S and the same number of Render Output Units. This results in the GeForce GT 620 providing 0.2 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 GeForce GT 620 was released less than a year after the HD i7 3770S, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 620 has 1024 MB video memory, but the HD i7 3770S does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i7 3770S has 16 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the HD i7 3770S is 74 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 60 better shader performance is not particularly notable, as altogether the HD i7 3770S performs better when taking into account other relevant data.

The HD i7 3770S transistor size technology is 18 nm (nanometers) smaller than the GeForce GT 620. This means that the HD i7 3770S is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 620. While they exhibit similar graphical performance, the HD i7 3770S should consume less power than the GeForce GT 620.

The HD i7 3770S requires 77 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 3770S and a PSU with at least 300 Watts for the GeForce GT 620. The HD i7 3770S requires 28 Watts more than the GeForce GT 620 to run. The difference is not significant enough for the HD i7 3770S to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 620.

GPU Mini Review

Mini ReviewOverview
Intel HD i7 3770S is the specific version of Intel HD Graphics 4000 Desktop that is Integrated in the Core i7-3770S Processor.

GPU
The Central Unit Initially Runs at 650MHz and goes up to 1150MHz, in Turbo Mode.

Memory
Frame Buffer: Up to 1.7GB.

Memory Channel: 64-bit Or 128-bit.

Memory Clock: Up to 800MHz.

Memory Bandwidth: It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Performance
Gaming Benchmarks Indicate its Performance is Similar to of a Dedicated GeForce GT 620.

System Suggestions
We recommend 4GB of RAM for a system with Intel HD i7 3770S.
Overview
GeForce GT 620 is an Entry-Level 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 Fermi GF108-100-KB-A1 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 700MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 500MHz.

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

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 49W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance is somewhat better than Radeon HD 7470.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 620.
