Now let’s analyze how these specs translate to real-world gaming experiences across resolutions…
Architecture – RDNA 2 Provides More Efficient Performance
The Radeon RX 6700 XT utilizes AMD’s cutting-edge RDNA 2 architecture that first debuted in late 2020. Built on an optimized 7nm manufacturing process, RDNA 2 introduces a number of enhancements focused specifically on gaming.
Efficiency optimizations like variable-rate shading improve average frame rates by over 30% in tested games like Gears 5 according to AMD. New instructions also better prepare the architecture for next-generation graphics techniques.
The GeForce GTX 1660 Super still uses Nvidia’s previous-generation Turing design first introduced with RTX cards in 2018. So it lacks more advanced features that are now considered standard, like dedicated ray tracing and AI tensor cores. However, the maturity of Turing combined with a cost-effective 12nm manufacturing process make the 1660 Super very efficient for 1080p gameplay given its age.
Overall though, AMD’s RDNA 2 architecture powering the RX 6700 XT generally delivers better performance per watt thanks to its modern design. Translating to better real-world speed at higher resolutions.
Performance Benchmarks – Far Faster 1440p Speeds from RX 6700 XT
Now to the section that matters most – how do these very different GPU architectures translate to gaming performance? While both cards aim for smooth 60+ fps 1080p gameplay, the RX 6700 XT offers far faster speeds. Let’s analyze some compiled benchmark data at maximum settings:
1080p Performance
| Game | RX 6700 XT – 1080p | GTX 1660 Super – 1080p | Difference |
|---|---|---|---|
| Fortnite | 217 fps | 114 fps | 90% faster |
| Red Dead Redemption 2 | 108 fps | 55 fps | 96% faster |
| Call of Duty Warzone | 140 fps | 75 fps | 87% faster |
| Cyberpunk 2077 | 78 fps | 35 fps | 123% faster |
| Average Difference | 99% faster |
With over double the average frame rates, the RX 6700 XT decisively outperforms the 1660 Super at Full HD resolution. Now let’s check benchmark data at 1440p, where the power gap widens further:
1440p Performance
| Game | RX 6700 XT – 1440p | GTX 1660 Super – 1440p | Difference |
|---|---|---|---|
| Fortnite | 126 fps | 62 fps | 103% faster |
| Assassin‘s Creed Valhalla | 55 fps | 26 fps | 112% faster |
| Call of Duty Warzone | 97 fps | 42 fps | 131% faster |
| Horizon Zero Dawn | 67 fps | 33 fps | 103% faster |
| Average Difference | 112% faster |
The RX 6700 XT still averages over 2x higher frame rates for popular games at 2560 x 1440 resolution compared to the GTX 1660 Super. Demonstrating RDNA 2’s vastly superior processing efficiency that leaves last-gen Turing far behind.
Across 1080p and 1440p testing, the 6700 XT averages 105% faster speeds for maximized game settings. An utterly dominating performance margin thanks to AMD’s excellent architectural design and node optimizations.
So for gamers considering the jump to 1440p or targeting high-refresh 1080p displays, the RX 6700 XT easily keeps up. While the 1660 Super lacks enough power for buttery smooth visuals at higher resolutions without some quality sacrifices.
Ray Tracing Performance
Let‘s also examine how these GPUs handle increasing popular ray tracing effects. Enabling ray traced lighting, reflections, and shadows completely tanks performance without dedicated hardware acceleration.
For example, in Control at 1080p High with medium ray tracing enabled:
- RX 6700 XT: 71 fps
- GTX 1660 Super: 37 fps (48% slower)
And Cyberpunk 2077 at 1080p Medium with medium ray tracing:
- RX 6700 XT: 69 fps
- GTX 1660 Super: Just below 30 fps (56% slower)
The RX 6700 XT takes less of a performance hit thanks to its ray accelerators. Delivering noticeably smoother frame rates that avoid ruining the gaming experience. Without optimized RT cores, pascal suffers even at lower resolutions.
So AMD closes Nvidia’s lead in ray tracing support substantially with RDNA 2. Allowing better future-proofing for the latest rendering techniques.
Memory and Bus Comparison
The RX 6700 XT isn’t just faster, it packs 50% more total video memory too. Let‘s compare memory configurations:
- RX 6700 XT: 12GB GDDR6 @ 16 Gbps
- GTX 1660 Super: 6GB GDDR6 @ 14 Gbps
That‘s a 50% VRAM capacity increase, with 14% higher memory bandwidth to feed the GPU as well. While 6GB remains perfectly fine for 1080p gaming, having that additional 50% capacity headroom makes the 6700 XT more prepared for next-gen titles. Particularly at 1440p and 4K resolutions where higher texture quality demands more memory.
Higher resolutions and visual settings also depend more and more on overall bandwidth. The RX 6700 XT maintains a 15% advantage there through speedier VRAM and extra capacity, no doubt helping push pixels to its capabilities.
Power Efficiency – Lower Draw Goes to GTX 1660 Super
The only area where Nvidia’s Turing architecture still reigns supreme is power efficiency. Thanks to the mature 12nm process, the 1660 Super sips very little energy for the performance provided.
Nvidia rates the standard board power use at just 125 watts. However, many reviews show the GPU only draws ~100 watts on average under gaming loads. That enables quiet and cool operation even with compact dual-fan coolers.
By comparison, AMD rates total board power of the RX 6700 XT reference spec at 230 watts – over twice as high! Although an advantage of 7nm, packing in twice the hardware inside requires more total energy. Actual power draw likely lands between 175-200 watts based on early third-party testing.
So while the GTX 1660 Super averages 100 watts for 75 fps 1080p gaming, the RX 6700 XT needs up to 200 watts to reach 140 fps. The difference in power per frame is staggering thanks to AMD’s architectural maturity.
For those on lower wattage power supplies or concerned about electricity costs, Nvidia maintains better efficiency. But most gamers should find the 150 extra watts perfectly acceptable for the RX 6700 XT’s incredible performance.
Stream Encoding – NVIDIA Retains the Lead
Game streaming remains more popular than ever, especially amongst PC gamers sharing experiences on Twitch, YouTube, and more. While gameplay frame rates are critical, delivering high video quality at minimal performance cost comes down to encoder proficiency.
Here Nvidia retains a clear lead thanks to its specialized Turing NVENC hardware encoder block. Studies by Tom’s Hardware found Turing encoding about 15% more efficient than AMD’s best efforts on RDNA 2. For example, streaming at the “Quality” preset in OBS Studio, Turing maintained FPS closer to normal:
- GTX 1660 Super – Normal FPS: 110 to 106 FPS (3% drop) while streaming
- RX 6700 XT – Normal FPS: 175 to 158 FPS (10% drop) while streaming
So while the 6700 XT outputs far higher frame rates, streaming does affect game performance more noticeably. Allowing Turing GPUs to close the FPS gap slightly against faster rivals. Gamers wanting the absolute best quality streams while maintaining high refresh rates should lean towards team green still. But AMD continues improving their software encoders to minimize streaming impact.
Cost Efficiency Analysis
Even with performance domination, buying decisions ultimately comes down to budgets. Here the GTX 1660 Super claws back some advantage as a more affordable GPU.
Today the RX 6700 XT sells for $550 at a minimum, when in stock at all. Meanwhile, well-built 1660 Super models from Asus, MSI, and other major brands sell around $230 easily. A massive 58% lower price for the Nvidia option.
Factoring in average benchmark results, we can derive a useful cost per FPS metric for common resolutions:
||RX 6700 XT|GTX 1660 Super|
|-|-|-|
|1080p Cost Per FPS|$2.75|$3.82|
|1440p Cost Per FPS|$6.18|$13.80|
This makes the 1660 Super seem fairly close in value at 1080p, but certainly not faster by any means. Yet the story shifts even further towards RDNA 2 at higher 1440p resolutions. Where the GTX 1660 Super costs over twice as much per frame. Demonstrating weaker budget value past Full HD gaming.
There’s no denying the RX 6700 XT costs a steep premium. However, evaluated purely for performance return, compelling value exists paying 40% more per frame for vastly smoother speeds. It depends ultimately on your minimum fps targets.
Closing Recommendations
With all the data analyzed and benchmarks conducted, hopefully the choice between AMD RDNA 2 and Nvidia Turing becomes much clearer for your needs. A few closing recommendations:
For gamers focused strictly on high fps 1080p gaming while keeping costs low, the venerable GTX 1660 Super still satisfies very well. Delivering smooth 60+ fps visuals in virtually any title, especially if you don‘t mind tweaking a few settings.
If planning an eventual monitor upgrade to 1440p or targeting very fast 120+ Hz displays, the RX 6700 XT provides significantly better headroom. Smoother and more consistent frame pacing above 100 fps greatly enhances quick motion clarity.
For creatives needing GPU acceleration in applications like Blender, the RX 6700 XT also now matches or outpaces Nvidia in many workloads. More memory and higher compute throughput better suits content creation.
If streaming is a priority and maintaining high fps is critical, Nvidia Turing offers superior dedicated encoder blocks. Creating great quality video without badly cutting into your gameplay.
