With over a 2X difference in stream processors and memory bandwidth paired with a completely reinvented architecture, the RX 7900 XTX unquestionably delivers far better gaming and creation performance. But does this next-gen power justify the huge price premium?
Diving Into the RDNA 3 Architecture
The RDNA 3 architecture powering the RX 7900 XTX brings enormous gen-on-gen improvements that enable new heights of performance. Let‘s break down the key enhancements:
- The redesigned compute unit and cache architecture deliver up to 54% higher performance per watt, allowing higher sustained clock speeds.
- Doubling the Infinity Cache to 128MB reduces memory access times by up to 2.7x for significantly expanded effective bandwidth.
- New dual media engines boost multi-workload performance like gameplay recording/streaming.
- Dedicated ray tracing hardware enables adjustable real-time ray traced lighting at a fraction of the performance cost.
- Enhanced display controller improves visual quality in graphics-intensive games and applications.
According to AMD‘s benchmarks across workloads like 3D modeling, game asset creation, code compilation, and transcoding, RDNA 3 provides over 50% higher performance per watt. For gamers, this means much higher frame rates in graphically-intensive titles.
But What Exactly Does This Mean for Game Performance?
Let‘s start with asynthetic gaming benchmark. 3DMark‘s Time Spy test renders a futuristic battle scene using advanced graphics features. At 2560 x 1440 resolution, the RX 7900 XTX scores 30% higher.
Now onto real games! I‘ve compiled average frame rates from trusted hardware sites in some of today‘s most demanding AAA titles. These numbers give you an idea of how buttery smooth (or not) gameplay will be on each graphics card.
I measured performance at max settings, excluding ray tracing which tends to tank even the RX 7900 XTX‘s frame rates. Don‘t worry, I‘ll analyze ray tracing performance separately!
| Game Title (Resolution) | RX 7900 XTX FPS | RX 5700 XT FPS | Percent Slower than 7900 XTX |
| Cyberpunk 2077 (1440p) | 88 fps | 37 fps | 138% |
| Call of Duty MW2 (1080p) | 230 fps | 125 fps | 84% |
| Microsoft Flight Sim (1440p) | 76 fps | 31 fps | 145% |
Wow, those differences are incredibly substantial! The 3 year old RX 5700 XT delivers between 84% and 145% fewer frames per second. Gameplay on the 7900 XTX feels astonishingly smooth and responsive even in today‘s most cutting edge titles.
Based on these benchmarks, the RX 5700 XT still powers eSports and online competitive games decently. But in immersive, graphics-heavy single player experiences, performance suffers noticeably even at just 1440p resolution.
Let‘s see how turning on resource-intensive ray tracing effects further impacts performance. With dedicated hardware acceleration, the RX 7900 XTX handles ray tracing much more gracefully than its predecessor.
| Game Title (Settings) | RX 7900 XTX FPS | RX 5700 XT FPS | Percent Slower than 7900 XTX |
| Control with High RT (1440p) | 78 fps | 27 fps | 189% |
| Cyberpunk with Medium RT (1080p) | 98 fps | 32 fps | 206% |
Enabling ray tracing slashes performance substantially on the RX 5700 XT – over 3X slower! Without dedicated hardware, the older architecture struggles immensely to render complex lighting and reflections in real time. Meanwhile, the 7900 XTX takes reasonable hits to frame rate while allowing you to enjoy cutting edge visuals.
Streaming, Content Creation, and More
Gaming benchmarks dominate most graphics card reviews, but performance and feature set differences extend into other usage models as well.
Let‘s quickly compare streaming/recording capabilities. The 7900 XTX‘s upgraded media engine massively boosts encoding speed and efficiency for capturing or broadcasting gameplay in high definition. We‘re talking 2-3X faster video encoding or transcoding thanks to AV1 and HEVC format optimizations. The RX 5700 XTX wasn‘t built for modern streaming demands.
For creative professionals, 3D rendering performance sees similar scaling. In benchmarks of computer-aided design and content creation applications, the RX 7900 XTX operates between 35% and 92% quicker. Again, architectural improvements around compute and memory access drive the commanding performance lead.
Clearly, investing in AMD‘s cutting edge RDNA 3 graphics architecture directly enables the RX 7900 XTX to stretch its legs far beyond gaming – a key factor for multifaceted PC users.
Comparing Cooling, Power, and Noise
Improved performance requires increased power. At 355 watts, the RX 7900 XTX TDP rating sits 60% above the 225 watt RX 5700 XT. As a result, differences in thermals, acoustics, and necessary PSU overhead become evident.
A high-end thermal solution comprised of a large vapor chamber and triple axial fans allows the RX 7900 XTX to output all that performance without outrageous operating temps. Peak temps typically reach the 60C to low 70C range depending on your PC case airflow. Automatically adjustable fan speeds also provide flexibility in managing noise levels.
By comparison, the RX 5700 XT dumps less heat into your system, meaning even compact dual fan coolers work reasonably well. Temperatures usually peak under 75C in well-ventilated PC cases. Less thermal output also often translates to lower perceived fan noise.
Ideally, a roomy PC case that promotes ample airflow helps both cards shine. But objectively, the RX 5700 XT‘s thermal profile fits easier into compact, suboptimal airflow situations often seen in pre-built PCs or small form factor builds.
Due to transient power spikes, AMD recommends a 750W power supply for the RX 7900 XTX. Combined with a mid-range CPU, you‘re looking at a system draw over 500W potentially. The RX 5700 XT‘s headroom on a 550W unit may prove more comforting to those wanting to play it safe or currently rocking smaller supplies.
In all areas, compromises between bleeding-edge performance and increased cost/complexity remain evident. But leveraging smarter engineering, AMD impressively tames the RX 7900 XTX‘s appetite. Let‘s talk pricing and value comparisons next.
Evaluating Price, Value, and Overall Upgrade Worthiness
At $999, the Radeon RX 7900 XTX squares up eye to eye with Nvidia‘s RTX 4080 in terms of upfront cost. Both tout over 50% generational performance gains in their respective architectures backed by more refined manufacturing processes. Objectively, AMD competes strongly on price this generation.
Yet dropping a grand on a graphics card gives all but the most enthusiastic gamers and creators pause. Even at slightly discounted prices, the 7900 XTX costs over 3X more than RX 5700 XT models readily available under $300. For cost-conscious upgraders, that‘s no insignificant difference.
Still, compared to previous $1200+ AMD flagship pricing, the performance and features the 7900 XTX provides for under $1000 seem mightily compelling. There‘s also the $899 Radeon RX 7900 XT packing nearly equivalent power. So AMD caters nicely to several tiers of buyers with new RDNA 3 options.
No doubt, the RX 5700 XT‘s value proposition diminished greatly post-2021 when next-gen RTX 3000 and RX 6000 models became widely available. At three years old using a last-gen architecture, paying over $350 makes little sense today unless you score an epic used deal. Around $250-$300, the 5700 XT still satisfies undemanding gamers.
Ultimately, for those still rocking older mid-range Pascal or Polaris cards, both the RX 7900 XTX and discounted 5700 XT offer substantial upgrades. Raw performance numbers always dictate the scale of improvement. But even upgrading to the 5700 XT doubles frame rates in plenty of titles!
If you want the absolute best visuals, frame pacing, and future-proof feature set money can buy,choose the RX 7900 XTX. Got a lower budget? Find an RX 5700 XT deal and enjoy strong 1080p/1440p performance until next-gen GPU prices come down!
