Game GeForce RTX 2080 Ti SLI HD Pentium 4405U

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 2080 Ti SLI are massively better than the Intel HD Pentium 4405U.

The RTX 2080 Ti has a 1050 MHz higher core clock speed and 256 more Texture Mapping Units than the HD Pentium 4405U. This results in the RTX 2080 Ti providing 362.4 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 RTX 2080 Ti has a 1050 MHz higher core clock speed and 80 more Render Output Units than the HD Pentium 4405U. This results in the RTX 2080 Ti providing 116.4 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 RTX 2080 Ti was released over three years more recently than the HD Pentium 4405U, and so the RTX 2080 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD Pentium 4405U when running the latest games.

The RTX 2080 Ti has 11264 MB video memory, but the HD Pentium 4405U does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the HD Pentium 4405U has 12. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the HD Pentium 4405U is 91. The RTX 2080 Ti having 7025 better shader performance and an altogether better performance when taking into account other relevant data means that the RTX 2080 Ti delivers a massively smoother and more efficient experience when processing graphical data than the HD Pentium 4405U.

The RTX 2080 Ti transistor size technology is 2 nm (nanometers) smaller than the HD Pentium 4405U. This means that the RTX 2080 Ti is expected to run very slightly cooler and achieve higher clock frequencies than the HD Pentium 4405U.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the HD Pentium 4405U requires 15 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti. The RTX 2080 Ti requires 245 Watts more than the HD Pentium 4405U to run. The difference is significant enough that the RTX 2080 Ti may have an adverse affect on your yearly electricity bills in comparison to the HD Pentium 4405U.

GPU Mini Review

Mini ReviewOverview GeForce RTX 2080 Ti is the top RTX 20 Series graphics card and considered an Enthusiast graphics card based on the Turing architecture. Architecture The Turing architecture represents a process shrink down to 12nm compared to 14nm Pascal. The Turing architecture provides the world's first consumer support for real-time ray-tracing technology, or RTX. GPU It equips a GPU Codenamed TU102 which has 4352 Shader Processing Units, 272 TMUs and 88 ROPs. The central unit runs at 1350MHz and goes up to 1545MHz in Boost mode. It also has 544 Tensor Cores for AI purposes. Memory The GPU accesses an 11GB frame buffer of first-gen GDDR6 memory through a 352-bit memory interface, while the Memory clock operates at 1750MHz, or 14GHz effective. Power Consumption With a rated board TDP of 285W, it requires at least a 650W PSU with two 8-pin power connectors. System Suggestions GeForce RTX 2080 Ti is best suited for resolutions up to and including 3840x2160. We recommend a top-End Processor and at least 16GB of RAM for optimal performance.Overview
Intel HD Pentium 4405U is the specific version of Intel HD Graphics 510 Mobile that is integrated in the Pentium 4405U Processor.

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 GT1-U offers 12 Shader Processing Units, 8 TMUs and 4 ROPs.

GPU
The Central Unit Initially Runs at 300MHz and goes up to 950MHz, 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.
Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface.

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 525M.

System Suggestions
Intel HD Pentium 4405U is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
