(GPU) AMD Radeon R9 290X

(Profile updated as of 10th July. 2019)

Here it is! The mighty Radeon R9 290X graphics card, with its Hawaii GPU that is now almost legendary. The GPU that beat Kepler and half of Maxwell. *Nostalgia* Anyway I did a profile for it so here you go.

Graphics Card description

The R9 290X launched in 2013 as AMD's high-end graphics card for that year. It performed very well and almost universally beat NVIDIA's GeForce GTX 780, matching the Original TITAN in many cases. This prompted NVIDIA to release the GTX 780 Ti; with the fully enabled GK110 graphis processor. This card took back the performance crown but fast forward to 2019 and the 290X has the last laugh thanks to architectural longevity and an extra 1GB of video memory.



The Hawaii GPU is unique among relatively modern Graphics Processors in that it has a very wide (512-bit) memory interface using GDDR memory. THis requires a grand total of 16 DRAM (32-bit x 16) chips to fully populate, giving Hawaii's its distinctive memory layout. However, it's interesting to note that according to AMD, Hawaii's 512-bit is denser on the silicon die than Tahiti's 384-bit, due to density optimisations.



Graphics Card approximate 3D Performance

Sashleycat gaming performance rating (2019): Acceptable for 1080p medium/high settings 60 FPS



Today the once mighty R9 290X has fallen to the low-mid range in terms of performance, and it performs roughly similar to a GTX 1650, and a bit below the RX 570. Performance varies depending on the game due to resource distrubution differences between these GPUs. This makes Radeon R9 290X suitable for comfortable gaming at 1920x1080 with medium or high settings (not Ultra) at, or close to, 60 frames per second.


Notes

GPU Computing Power FP64

Hawaii processor has a native 1:2 rate of FP64:FP32, but it is throttled to 1:8 on the Radeon gaming cards.



Typical Board Power

Official Board Power is 250W but the actual board power is between 250 and 295W, on average.

Maximum Board Power

This is based on R9 290X board power of 250W (official) and +50% Power Limit.



Misc.

This bit is for my personal opinion on this Graphics card / Graphics processor
