Acer's overclocked RX 7800 XT cards arrive — Shadow Knight in China, Nitro in the US

Earlier today, Acer dropped its Nitro Shadow Knight RX 7800 XT in the Chinese market, just a few months after showing it off at CES 2024 [h/t ITHome.com]. Admittedly we didn't get our hands on it during the show— some other Acer oddities caught our attention at the time— but the latest "Shadow Knight" in Acer's lineup does seem interesting. The same card also launched as the "Nitro" in the U.S. and other areas, with the Acer Nitro RX 7800 XT priced at $519.99 at Newegg. That puts it in direct competition with the RTX 4070, and not far off the RX 7900 GRE, both of which are among the best graphics cards.

Our GPU benchmarks hierarchy puts the RX 7800 XT squarely between the RTX 4070 Super and RTX 4070 in rasterization performance. Ray tracing workloads as usual drop AMD quite a bit, with the RX 7800 XT performance landing just above the RTX 4060 Ti. Acer's card comes with a dual-fan 2.5-slot form factor, which may be a draw for those looking for something slightly more compact. Let's quickly look at the core specs.

Acer Nitro Shadow Knight RX 7800 XT Official Specifications

  • GPU Cores: 3840 RDNA 3 shaders / 60 Compute Units
  • GPU Core Clock: Up to 2565 MHz (Stock 7800 XT is 2430 MHz)
  • Ray Accelerators: 60 (1 per GPU core)
  • AI Accelerators: 120 (2 per GPU core)
  • GPU Memory: 16GB GDDR6 
  • GPU TGP: 281 Watts (Stock 7800 XT targets 263 Watts)
  • GPU Dimensions: 279 x 129.62 x 50.42 millimeters

Official base MSRP on the RX 7800 XT is $499, but pressure from the RTX 4070 and RX 7900 GRE has pushed the minimum cost GPU down to $479 for the ASRock 7800 XT at the time of writing. That makes the Acer model a more difficult sell, though the decent overclock on the GPU does help a bit. Given the rest of the market, we think the 7800 XT needs to come in well below $500 these days.

Acer also touts low noise as a benefit of the Nitro / Shadow Knight RX 7800 XT, and says the "Frost Blade" fans reduce noise levels by 2.4 decibels and increase airflow by as much as 9.7% (though we're not sure what it's using as a comparison point). Improved cooling noise levels, coupled with the increased TGP and Boost Clock, help the card stand out, at least on paper, but we'll have to see some independent testing before drawing any final verdict.

Ultimately, final pricing will end up making or breaking this card. A decent overclock should close the gap between it and the 7900 GRE / 4070 Super, though the former remains our primary pick. The market has no shortage of overpriced AIB cards, and data like the Steam Hardware Survey suggests AMD's RX 7000-series isn't doing too well against the RTX 40-series. Hopefully, Acer's foray into the dedicate GPU market can help bring prices down, as we've seen with its Arc-based offerings.

[Note: Our initial story didn't see the U.S. Nitro listings, which appear to be effectively the same, perhaps with a 5 MHz difference in boost clocks. We've updated the story to reflect the apparent worldwide availability of the Acer cards.]

    Acer actually just released a very similar model for the US, UK and rest of the world as well. Priced at $520 USD. Almost similar specs, since the Newegg listing has some errors.

    The above "Shadow Knight" branded SKU is a China-exclusive model. Check this out.

    Acer Nitro Shadow Knight RX 7800 XT Official SpecificationsGPU Cores: 60 AMD RDNA 3 Cores
    GPU Core Clock: Up to 2565 MHz (Stock 7800 XT boosts to 2430 MHz)

    Those are Compute Units which you have mentioned, 60 in total. The total cores/Stream Processors/Shading Units are 3840. Each CU has a single Ray Accelerator. Hence 60 RAs in total.

    Good catch!

    I've been thinking of RDNA GPUs in CUs because of all the APU coverage we do, my bad. Should have typed as much. Will try to get some appropriate edits pushed through the pipeline.

    BTW, all current Acer GPU models are retailing slightly above the official MSRP which isn't a good sign, given other AIBs are offering cheaper alternatives, and ACER is a new player in the discrete gaming GPU market.

    FWIW, a slight price reduction can surely make them more competitive here.

    But I'm sure the company will drop the price, since we have seen very "aggressive" price cuts and discounts on Intel's ARC lineup of discrete GPUs, notably with the A770, A750, and other variants.

    The higher end triple fan design Predator BIFROST 7800XT model is even more expensive, retails at $559.99. :devilish:

    No worries at all ! It happens with me as well.

    I just noticed that info, since I have a very bad weird habit of proof-reading any article I read online, let alone here on Tom's HW. :LOL: :)

    At $499-539, the $549-599 7900GRE is *much* more attractive.
    Esp. since most GRE examples (now) can do 2499-2501Mhz VRAM with ease.

    Admittedly, the 7800XT is a slightly smaller card but,
    if power/heat is an issue, an underclocked and undervolted GRE is an efficiency beast.
    The GRE is easily a ~100W 1080P card (under clocked).

    Hey, I feel your point of view as well.

    You know, I had forgotten than Acer was making Radeons because almost of all the Acers that have received coverage have been ARC GPUs. :LOL:

    I'm forced to wonder if there would be a problem with Sapphire because of the NITRO branding.

    Yeah, I was also wondering about the NITRO branding used by Acer and Sapphire, but I guess Acer's Nitro brand has it's own market segment unlike Sapphire which only sells GPUs under the same brand ?

    Acer mostly sells Laptops under the Nitro brand (unless I'm mistaken), so I'm guessing both companies have their own rights with regards to the branding, and they won't fall into any kind of legal issues, imo ?

    But Acer also using the same Nitro sub-brand for it's upcoming gaming GPUs sounds a bit odd to me as well.

    But again, I'm not sure how companies work their trademark issues, and how they deal with such cases. Let's call a Lawyer here, hehe.

    :unsure:

    Honestly, I don't know why Acer would even try it. IMO, "BiFrost" is way more awesome a name for a video card.

    It reminds me of the good ol' days with names like HIS' ICE-Q and MSi's Twin Frozr models. If I made video cards, I'd give them model names like "Sub-Arctic" and "Cryo-Chamber". It always helps when you use "cool" names, eh? ;)(y):ROFLMAO:
