ATi HD 4870 X2 Review

There are graphics cards, and then there are moments in GPU history. The ATi HD 4870 X2 is firmly the latter — a dual-GPU behemoth from the AMD-ATi merger era that, even today, earns a loving 25-minute retrospective from Gamers Nexus' Steve Burke. That alone tells you something about this card's legacy.

What Made the 4870 X2 Special

When AMD and ATi merged, there was genuine uncertainty about whether the partnership would produce anything world-class. The HD 4870 X2 answered that question loudly. Two RV770 GPUs on a single PCB, connected via an internal bridge — it was AMD's answer to NVIDIA's dual-GPU designs, and by most accounts it competed ferociously at the top of the market the moment it launched.

The Gamers Nexus tear-down highlighted a prototype variant of this card, which is itself a remarkable artifact. The fact that a pre-production prototype survived long enough to be examined in detail speaks to just how significant this product was internally at AMD. As the Reddit community noted, it's the kind of video — and the kind of hardware — that "you don't see often" in today's content landscape.

The Dual-GPU Reality: Brilliant and Complicated

Here's the thing about dual-GPU cards from this era that any honest retrospective has to address: they were spectacular in benchmarks and genuinely frustrating in day-to-day use. The 4870 X2 was no exception.

CrossFireX scaling was impressive when it worked — and it often did work well in the titles of the time. But micro-stuttering was a real and documented issue across dual-GPU setups in this generation. Frame pacing technology simply wasn't where it needed to be, meaning that even when the average framerate looked stellar on paper, the actual experience could feel less smooth than those numbers suggested. For competitive gaming or anyone sensitive to frame delivery consistency, this was a genuine concern, not a minor footnote.

Power consumption and heat were also significant. Two RV770 chips under load drew serious wattage, demanded robust cooling, and made their presence known acoustically. This wasn't a card for small cases or modest power supplies.

Driver support for multi-GPU configurations in this period was inconsistent. Some games scaled beautifully; others barely used the second GPU at all. Buyers were, in effect, betting on AMD's driver team to keep up — and that was a bet with variable returns.

As a Historical Artifact

Viewed through the lens of 2024, the 4870 X2 is a genuinely fascinating piece of hardware history. It represents a pivotal moment — AMD proving it could build a flagship-class product after absorbing ATi, and the industry at large still figuring out whether dual-GPU was a viable long-term strategy (spoiler: it largely wasn't, at least not in single-card form).

The Gamers Nexus community on Reddit was clearly appreciative of Steve taking a slower, more reflective approach to covering it. One commenter summed it up well: it's rare to see tech content that steps back from the relentless churn of new releases to examine where we came from. The 4870 X2 is exactly the kind of product that deserves that treatment.

Who Is This "For" Today?

If you're a collector of vintage GPU hardware, a hardware historian, or simply someone who wants a striking conversation piece from a genuinely important era in graphics card development — the 4870 X2 is a trophy. Finding a working unit is increasingly rare, and a prototype variant as examined by Gamers Nexus is essentially a museum piece.

For anyone considering it as actual gaming hardware in a modern system: don't. Driver support is long gone, modern APIs are incompatible, and anything it could run is better served by budget-tier current-generation cards that cost a fraction of what a good 4870 X2 specimen would command from a collector.

Frequently Asked Questions

Q: Is the ATi HD 4870 X2 still usable for gaming today?

A: Practically speaking, no. Modern game engines, APIs like DirectX 12 and Vulkan, and the complete absence of driver support make it unsuitable for any current gaming use. It is a collector's item, not a gaming card.

Q: What was the HD 4870 X2's main advantage when it launched?

A: It packed two RV770 GPUs on a single card, giving it benchmark performance that competed directly with NVIDIA's best at the time. It was AMD's statement card following the ATi merger and demonstrated the company could build flagship-tier hardware.

Q: What were the biggest drawbacks of the 4870 X2?

A: Micro-stuttering from inconsistent frame pacing, high power draw, significant heat output, and uneven game compatibility with CrossFireX scaling were the main real-world complaints. It was a card that demanded a lot from your system and your patience with drivers.

Q: Where can I learn more about the 4870 X2's history and design?

A: Gamers Nexus published a dedicated tear-down and retrospective video covering a rare prototype unit, which the hardware community on Reddit highlighted as an unusually detailed and relaxed look at this GPU's history — well worth watching for enthusiasts.

Q: Is the prototype version different from the retail 4870 X2?

A: Yes — the prototype examined by Gamers Nexus shows pre-production design choices that differ from the final retail card. These variants are extremely rare and represent a snapshot of the card's development process rather than what consumers actually purchased.

The HD 4870 X2 earns its legendary status. As a product it was ambitious, technically impressive, and genuinely competitive — but also demanding, occasionally temperamental, and dependent on software that AMD didn't always deliver consistently. As a piece of history, it's priceless. The four stars here are for what it was in its time: a bold, important GPU that pushed AMD back into the flagship conversation and gave NVIDIA a real fight. That's worth remembering.
