Game GeForce RTX 2080 Ti SLI GeForce GTX 650 Ti Boost Edition SLI

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 2080 Ti SLI are massively better than the Nvidia GeForce GTX 650 Ti Boost Edition SLI.

The RTX 2080 Ti has a 370 MHz higher core clock speed and 144 more Texture Mapping Units than the GTX 650 Ti. This results in the RTX 2080 Ti providing 241.8 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 370 MHz higher core clock speed and 40 more Render Output Units than the GTX 650 Ti. This results in the RTX 2080 Ti providing 71.8 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 GTX 650 Ti, 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 GTX 650 Ti when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The RTX 2080 Ti has 7168 MB more video memory than the GTX 650 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RTX 2080 Ti also has superior memory performance overall.

The RTX 2080 Ti has 327.6 GB/sec greater memory bandwidth than the GTX 650 Ti, which means that the memory performance of the RTX 2080 Ti is massively better than the GTX 650 Ti.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the GeForce GTX 650 Ti Boost Edition SLI has 1536. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the GTX 650 Ti is 1587. The RTX 2080 Ti having 5529 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 GTX 650 Ti.

The RTX 2080 Ti transistor size technology is 16 nm (nanometers) smaller than the GTX 650 Ti. This means that the RTX 2080 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 650 Ti.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the GeForce GTX 650 Ti Boost Edition SLI requires 268 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti and a PSU with at least 650 Watts for the GTX 650 Ti. The GTX 650 Ti requires 8 Watts more than the RTX 2080 Ti to run. The difference is not significant enough for the GTX 650 Ti to have a noticeably larger impact on your yearly electricity bills than the RTX 2080 Ti.

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.NOTE: THE REGULAR GEFORCE GTX 650 TI DOES NOT SUPPORT SLI!!
GeForce GTX 650 Ti Boost Edition SLI is a combination of two GeForce GTX 650 Ti Boost Edition, using NVIDIA's SLI technology.
Know that SLI relies a lot on proper driver support and the game itself might not be optimized for this technology. Therefore, this combination's rank is based on an overall performance boost of 2010 to today's modern games.
GeForce GTX 650 Ti Boost Edition SLI offers two Kepler GK106 Cores and thus a total of 1536 Shader Processing Units, 128 TMUs and 48 ROPs, on a 384-bit of fast GDDR5. The central unit runs at 980MHz and goes up to 1033MHz in Turbo Mode. This combination is expected to consume up to 268 Watt, though the average power consumption, under load, should be lower.
Due do its similarities to a single GeForce GTX 680, it's expected to offer better performance than it. However, remember the SLI problems.
Overall, this combination performs slightly better than a single GeForce GTX 680, costs less, but consumes more power.
