GeForce GT 1030 vs Radeon RX 550


The GeForce GT 1030 features a clock frequency of 1265 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 64-bit bus, and makes use of a 16 nm design. It features 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon RX 550, which has GPU core speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also features 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 1030 49152 MB/sec
Difference: 65536 (133%)

Texel Rate

The GeForce GT 1030 will be a little bit (about 15%) better at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 5280 (15%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 1030 is a better choice, but only just. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 2640 (15%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

Hello, i need to know if this graphics card MSI Radeon RX 550 2GB Aero ITX OC supports HDCP 2.2 and play at resolution 3840x2160 60hz and if these cards also MSI Radeon RX 460 2GB OC or MSI GeForce GT 1030 2GB or other and you reccomend me to choose for connecting on 4K UHDTV hdr HDMI v 2.0b HDCP 2.2 compatible mainly for watching movies with mpc-hc in an old pc desktop psu 450 watt, proccessor amd athlon II x4 640 , 4gb ram , i am not interest for games and must have the above i mentioned. Thanks in advance
