NVIDIA GeForce GTX 1060 3GB vs AMD Radeon RX 460

On paper, the NVIDIA GeForce GTX 1060 3GB carries more memory (3 GB against 2 GB), the NVIDIA GeForce GTX 1060 3GB has more shading units, and the NVIDIA GeForce GTX 1060 3GB has a wider memory bus. Specifications describe what each card is designed to do; how much of that either one holds under continuous load is a separate question.

A check marks the higher figure only on rows where higher is unambiguously better. Rows without one are not ties; they are specifications where “better” has no meaning.

Reading the table

What the difference means.

Video memory

The GTX 1060 3GB has 3 GB of video memory against 2 GB. Memory does not make a card faster until it runs out, and then the drop is sharp: textures spill into system memory and frame times stutter. High resolutions, high texture settings, heavy mods and running AI models locally are what fill it. 2 GB is already the limit in some recent games at high settings.

Memory bus

The GTX 1060 3GB moves data over a 192-bit bus of GDDR5; the RX 460 uses 128-bit GDDR5. The bus width and the memory type together set how fast the chip can reach its own memory, which shows at high resolutions where every frame moves more data. A narrow bus with fast memory can match a wide one with slow memory, so neither figure settles it alone.

Shading units

The counts differ, 1,152 against 896, but these are different designs from different makers, and a shading unit on one is not the same amount of work as on the other. The row cannot be used to rank this pair.

Board power

The GTX 1060 3GB draws up to 120 W against 70 W. That is heat the case has to exhaust and current the power supply has to deliver: allow a supply of about 500 W for the GTX 1060 3GB with a typical processor, and check the card's power connectors against the supply's. A card that cannot shed its heat does not fail. It lowers its clocks after a few minutes, which is the frame rate that falls the longer you play.

Which to pick, on paper

High resolutions, heavy textures, local AI: GTX 1060 3GB; 3 GB against 2 GB. Memory is the wall these workloads hit first.
A small case or a modest power supply: RX 460; 70 W against 120 W: less heat, fewer power connectors, quieter fans.

What no table says

How much of its speed a graphics card keeps after the first minute depends on the cooling and the power limit of the machine it is in. If you own one of these, measure it: the test is free and runs in this browser.

Questions

Is the GTX 1060 3GB better than the RX 460?: By need, on the specifications: high resolutions, heavy textures, local ai: the GTX 1060 3GB; a small case or a modest power supply: the RX 460. They are different designs, so the raw counts cannot rank them. Frame rates depend on the game and its settings, and how much speed either card keeps after ten minutes depends on its cooling, which is what a sustained test measures.
Is 2 GB of video memory enough?: For 1080p at sensible settings, only in older or lighter games. At 1440p and above, with high texture settings, or for running AI models, 3 GB gives real headroom. When memory runs out the symptom is stutter, not a lower average.
What power supply does the GTX 1060 3GB need?: Allow about 500 W with a typical processor, and make sure the supply has the power connectors the card uses. The RX 460 at 70 W is easier on both.

More comparisons

Every figure on this table is a design target. None of it is a measurement.

Nothing above describes how a graphics card behaves twenty minutes into a sustained workload, which is where two chips with nearly identical specifications routinely diverge. A boost clock is a ceiling the vendor permits, not a rate the chip sustains, and whether it holds depends on the cooling, the case, the power profile and the room. None of those appear on a specification sheet.

We deliberately do not reduce these figures to a single score. A composite invented from specifications would look authoritative and measure nothing, and choosing the weights would be choosing the winner.
