The performance is clearly faster than the old RX Vega 8 thanks to the higher clock speed and faster main memory (if used). More information is available in our dedicated article about the Raven Ridge architecture. The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. Compared to the similar Radeon RX Vega 8 in the Raven Ridge generation (Ryzen 2000 Mobile), the GPU is clocked significantly higher (1.750 versus 1.100 MHz Boost, +59%). The GPU should benefit from fast dual-channel DDR4-3200 RAM (contrary to DDR4-2133 single-channel, which is also possible). The performance depends on the configured TDP (12-25 W at launch), the clocks, the cooling, and the memory configuration). The GPU is based on the Vega architecture (5th generation GCN) and has 8 CUs (= 512 of the 704 shaders) clocked at up to 1.750 MHz (Ryzen 7 4800U). It is used for the Ryzen 7 APUs of the Renoir generation (Ryzen 4000 Mobile), which were announced in early 2020.
The AMD Radeon RX Vega 8 is an integrated GPU for notebooks. The Geforce GTX 660Ti is rated at 150 Watt TDP and the default design uses two 6-pin power connectors.īeware: For our benchmarks we used a slightly overclocked version that ran with 980-1059 MHz compared to the default 915 - 980 MHz.ĪMD Radeon RX Vega 8 (Ryzen 4000) ► remove from comparison Furthermore, the included vidoe encoder called NVENC is able to encode H.264 vidoes without stressing the CPU. The chip offers the 5th generation video processor VP5, which is able to decode MPEG-1, 2, 4, H.264, VC1/WMV9 with a resolution of up to 4K. Only Company of Heroes 2 and Hitman: Absolution scored below 30fps in our benchmarks on the average. Demanding games of 2013 should run in 1920x1080 with maximum settings and 4x Antialiasing fluently. The GDDR5 VRAM is usually clocked at 1500 MHz (6000 MHz effective data rate).ĭue to the higher core clock speed, the performance of the desktop GTX 660Ti is above the mobile GTX 680M (altough the 680M offers a wider memory bus of 256 Bit). The core clock can be up to 980 MHz under load (GeForce Boost) and is a tleast 915 MHz. It supports DirectX 11 and is manufactured in 28nm at TSMC.

GeForce GTX 650 Ti is connected to the rest of the system using a PCI-Express 3.0 x16 interface. Display outputs include: 2x DVI, 1x mini-HDMI. The GPU is operating at a frequency of 928 MHz, memory is running at 1350 MHz (5.4 Gbps effective).īeing a single-slot card, the NVIDIA GeForce GTX 650 Ti draws power from 1x 6-pin power connector, with power draw rated at 110 W maximum. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GTX 650 Ti, which are connected using a 128-bit memory interface. It features 768 shading units, 64 texture mapping units, and 16 ROPs. Unlike the fully unlocked GeForce GTX 660, which uses the same GPU but has all 960 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 650 Ti to reach the product's target shader count. The GK106 graphics processor is an average sized chip with a die area of 221 mm² and 2,540 million transistors. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. Built on the 28 nm process, and based on the GK106 graphics processor, in its GK106-220-A1 variant, the card supports DirectX 12.
The GeForce GTX 650 Ti was a mid-range graphics card by NVIDIA, launched on October 9th, 2012.
