Radeon R5 M330 vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has set the core speed at 1247 MHz. The HBM2 memory works at a frequency of 1890 MHz on this specific card. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX Vega 64 should perform a lot faster than the Radeon R5 M330 in general. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 481011 (3340%)

Texel Rate

The Radeon RX Vega 64 should be much (approximately 1450%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 298632 (1450%)

Pixel Rate

The Radeon RX Vega 64 will be much (more or less 869%) faster with regards to full screen anti-aliasing than the Radeon R5 M330, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 71568 (869%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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