Samsung Odyssey OLED G8 vs Alienware AW3423DWF: Price

Right now, the Samsung Odyssey OLED G8 is available for $1,499 from the Samsung store. Conversely, you can get the Alienware AW3423DWF for $999 on Dell’s website.

Alienware’s gaming monitor is $500 less than Samsung’s, which will no doubt make it the winner for budget-minded folks.

Samsung Odyssey OLED G8 vs Alienware AW3423DWF: Design 

The Odyssey OLED G8 is a striking gaming monitor thanks to its all-silver plastic chassis and the RGB lighting surrounding its monitor mount on the back. At 32.3 x 18.0 x 7.3 inches and a weight of 16.5 pounds, the Odyssey OLED G8 is somewhat large and heavy, though not extremely so.

Its L-shaped stand doesn’t occupy much desk space, and there’s a convenient opening to slip cables through — which further minimizes desk clutter. I appreciate how easy it is to raise or lower the monitor to my preferred height.

Port selection is as minimal as the monitor’s design. On the monitor’s lower back, you’ll find a single Mini DP 2 port, a Micro HDMI port and two USB-C ports. Unfortunately, standard DisplayPort and HDMI cables aren’t compatible with the Odyssey OLED G8. There’s also an OSD (on-screen display) joystick to bring up and move through the main menu.

The Alienware AW3423DWF is a gaming monitor through and through. At 32.1 x 16.3 x 12 inches and 21 pounds, it’s thicker and heavier than Samsung’s monitor. Like the Odyssey OLED G8, it has a sleek 1,800R curved display that nicely wraps around your field of view. Save for a “34” and Alienware’s signature alien logo on the back, the chassis is entirely black — which gives the monitor a slightly menacing appearance. The Legend 2 AlienFX lighting on the back adds some flair, even if you don’t see said lights when using the monitor.

The V-shaped base stand takes up considerable space on a desk. That said, it’s not hard to raise or lower the monitor along the stand’s shaft. Similar to Samsung’s monitor, you’ll have no issues positioning the monitor to your preferred viewing angle.

Unlike the Odyssey OLED G8, you’ll find plenty of connectivity options. This includes an HDMI 2.1 port, a pair of DisplayPorts, four USB-A ports, a headphone jack and a line-out port. Beneath the monitor, you’ll find an OSD (on-screen display) joystick used for entering the menu to configure display settings.

Both monitors have sleek, futuristic designs that help them look great on one’s desk. Their respective RGB lighting also cements them as gaming monitors. That said, the Odyssey OLED G8 is thinner and lighter, and it takes up less space.

Samsung Odyssey OLED G8 vs Alienware AW3423DWF: Display 

Both the Odyssey OLED G8 and Alienware AW3423DWF have 34-inch (3,440 x 1,440) displays with a 1,800R curvature. Their displays are equally as immersive — not to mention as sharp and colorful. But how did they fare in our lab tests?

When we pointed our Klein-10A colorimeter at the Odyssey OLED G8, we found that the Odyssey OLED G8’s screen achieved an average brightness of 240 nits of brightness in Standard mode. That’s on par with the Alienware AW3423DWF with its 236 nits of brightness.

Delta-E0.120.24

The monitors also produce oversaturated colors. In Standard mode, the Odyssey OLED G8 display covered 183.3% of the sRGB color gamut and 129.9% of the more demanding DCI-P3 color space (closer to 100% is best), with a Delta-E value of 0.12 (closer to 0 is ideal). We saw these values across most of its display modes.

In its Standard mode, the AW3423DWF covered 180% of the sRGB color gamut and 127% of the DCI-P3 gamut, with a Delta-E value of 0.24. Samsung’s monitor had a better Delta-E score but overall, color-accuracy is the same on both devices.

It’s hard to choose a winner in this category since both monitors are fairly even in terms of color and brightness. I love the way games like Doom Eternal and Cyberpunk 2077 looked on each monitor. The oversaturated colors and rich detail provided by the 2.5K resolution drew me into those respective worlds. In short, both the Odyssey OLED G8 and AW3423DWF provide an enjoyable viewing experience for gaming.

Samsung Odyssey OLED G8 vs Alienware AW3423DWF: Performance 

The Odyssey OLED G8 and Alienware AW3423DWF deliver rock-solid performance thanks to their high refresh rates and low response times. Both monitors support Adaptive Sync and AMD FreeSync Premium Pro, which also ensures games run at their best. While neither monitor is G-Sync certified, their respective VRR tech ensures a smooth gaming experience for those with Nvidia GPUs.

To test both monitors, I connected them to the Dell XPS 8950, which has a 12th gen Intel Core i5-12600k processor, an Nvidia GeForce RTX 3060 Ti GPU and 16GB of RAM. Thanks to that system’s specs, Doom Eternal ran at around 160 frames per second at high settings. The Odyssey OLED G8 (175Hz) and AW3423DWF (165Hz) deftly handled such high frame rates.

On paper, the Odyssey OLED G8 has a higher refresh rate and a lower response time than the AW3423DWF. If you’re a competitive gamer, I’m sure you’ll notice the difference. However, if you’re a semi-hardcore player like me, the difference is negligible. I didn’t notice a significant performance difference in the fast-paced Doom Eternal on Samsung’s monitor versus Alienware’s.

Performance-wise, both monitors deliver the goods for most people. But if you need a competitive edge, the Odyssey OLED G8 should grant it.

Samsung Odyssey OLED G8 vs Alienware AW3423DWF: Interface/features 

The monitors have clean interfaces that are simple to navigate through. Where the Odyssey OLED G8 has a semi-transparent blue background with white lettering, the AW3423DWF’s interface features a black and grey background with blue and white lettering. The monitors’ respective OSD joysticks are equally responsive when cruising through menus.

The Alienware AW3423DWF has no additional features beyond those found in its main menu, which isn’t the case with Samsung’s monitor.  Like some of the recent best Samsung TVs, the Odyssey OLED G8 features the company’s smart TV and game hubs — which both utilize Samsung’s Tizen platform. The former has all the major streaming apps and some free content from Samsung TV Plus.

For gamers, you’ll find streaming apps like Xbox Game Pass, Nvidia GeForce Now and Amazon Luna. What’s great about that is you don’t need to own a console or gaming PC to enjoy games on the Odyssey OLED G8. All you need is to pair a gaming controller to the monitor and fire up one of the gaming apps.

Thanks to the built-in Samsung TV and game apps, the Odyssey OLED G8 is more versatile than the comparatively straightforward Alienware AW3423DWF. But if you just want a no-frills monitor for playing games locally from your PC, then perhaps Samsung’s apps won’t matter to you.

Samsung Odyssey OLED G8 vs Alienware AW3423DWF: Bottom line

I'm confident in recommending the Samsung Odyssey OLED G8 and Alienware AW3423DWF to anyone looking for an all-around great gaming monitor. They not only look great on your desk, but they also help immerse you in the best PC games, best PS5 games and best Xbox Series X games thanks to their vivid curved displays. There's a reason both are my favorite gaming monitors in recent years: they're spectacular.

You can't go wrong with either choice. However, the $500 price difference between the monitors could be the deciding factor for many of you. If a $1,500 gaming monitor is too much, then the Alienware AW3423DWF is the clear option. But if you value better specs (on paper) and want built-in smart TV and gaming apps, then the Samsung Odyssey OLED G8 is worth looking into.
