“To gaming and past!” “Infinity Mirror,” “Spectra ARGB,” “Icestorm 3.0,” and “as much as 9 composite heatpipes,” as a result of that sounds higher than explaining that the 5090 and 5080 are totally different. It even has a “card-length heatsink,” which is nice as a result of we’d somewhat have that than a backplate and followers extending previous the heatsink… And sure, the PCB is shorter than the heatsink.
Regardless of its worth, we’re nonetheless going to check this card and see if it’s designed nicely, we’re going to tear it down and search for issues. We’ll take a look at it thermally and acoustically as nicely.
We’re borrowing the cardboard from a system integrator as a result of we don’t need to work with the companions immediately for them nowadays and we haven’t been in a position to seize one after they go on sale. Provide seems to nonetheless be about 0. Let’s get into the testing of the Zotac 5080 Strong.
Overview
The previous couple of Zotac playing cards we checked out had main oversights of design. The worst one had an enormous heatsink that didn’t contact the MOSFETs. This card did not have that challenge.
Zotac’s web site says the “Strong” sequence is “no frills, all motion.” We don’t know what which means. It’s a video card.
The cardboard additionally has “a robust cooling system” “*obtainable on choose fashions.” Good. We just like the uncertainty of the product web page particular to this product.
The location additionally says:
“With a stealthier aesthetic and engineered for sturdiness and efficiency, the ZOTAC GAMING SOLID is for individuals who demand pure efficiency over the rest.”
As for precise options, it has an LED that alerts customers of an improperly inserted 12V-2×6 connector, a twin VBIOS change, a partial flow-through space on the again, and makes use of an enormous warmth sink. Sadly, the cardboard makes use of loads of plastic, together with on the again and its design blocks a few of the exhaust.
Zotac RTX 5080 Strong Tear-Down
Zotac’s RTX 5080 Strong is way bigger than the 5080 Founder’s Version model (learn our assessment), taking on over 3 slots. One good factor in regards to the card is that it makes use of a bigger bracket, which helps with structural rigidity.
The cardboard makes use of a typical 3-fan design however has a considerably giant flow-through space on the again. Sadly, Zotac’s design blocks off roughly 20% of the cardboard’s circulate by right here.
The cardboard comes with a 3 8-pin adapter for the cardboard’s 12V-2×6 connector.
The cardboard has a novel plastic “grill.”
The again is comparable with some perforated holes, however beneath, you’ll see loads of plastic obstructing airflow.
Measuring the followers, they’re 95mm ones and have a hoop across the outdoors, that are supposed to assist direct the airflow straight by a bit of extra. The primary 2 followers are going to push air straight into the PCB in a extra conventional method with the third fan pushing a few of the air out the again.
To take away the aluminum backplate, we merely take away a number of screws on the again, which expose roughly 2.5mm thick thermal pads that contact the bottom of the reminiscence and VRM.
Subsequent, we eliminated the cardboard’s backplate by eradicating some screws.
To take away the entrance plate, we, once more, eliminated some screws.
Shifting ahead, we eliminated one cable on the again.
From there, we eliminated the GPU’s leaf spring.
Eradicating this part of the PCB exposes 2 linked fan connectors, which we have to disconnect to proceed additional with the tear down.
From right here, we will see plastic across the GPU die, which is rare. We will additionally see that the cardboard additionally has 2 further 2mm clay-like thermal pads that cowl the cardboard’s inductors.
The cardboard additionally has 3 Zotac-branded fuses. From what we’ve heard some time again, these fuses received’t act quick sufficient to guard the cardboard however does assist the RMA heart assist establish the place the failure occurred.
Flipping the cardboard over, we will see a vapor chamber. We additionally see the reminiscence contacting a separate plate.
The GPU makes use of seven 6mm warmth pipes, which is so much.
The cardboard has thermal pads that make contact with the MOSFETs, which Zotac had a problem with previously.
We additionally observed a thermal pad that touches the cardboard’s R10 inductor.
The cardboard’s fan cables are very accessible, which is nice in case you’ve gotten a fan die in some unspecified time in the future.
Cleansing off the thermal paste from the 5080 GPU, we will see the GB203-400-A1 die, which is so much smaller than the 5090 die.
Subsequent, let’s transfer into our thermal testing.
Zotac RTX 5080 Strong Checks
Thermals – Equilibrium
We ran this previous to the tear-down in an effort to protect the cardboard as-is for testing. We examined each VBIOS choices for thermals and frequency.
In a fast head-to-head, examined utilizing the auto settings and no matter VBIOS tells the cardboard’s followers and clocks to do, we landed on these outcomes. The 5080 Founders Version card ran at 32 dBA in our hemi-anechoic chamber and pulled 315W board energy underneath this workload. These variables put the GPU temperature at 65 levels Celsius and reminiscence at 72.8 levels Celsius. The Zotac 5080 Strong examined with the identical software program and auto situations ran at 31.1 dBA and 360W. The workload doesn’t pin these to TDP, however is constant.
The Zotac card runs the next out-of-box energy funds and its increased clocks are pulling extra energy. Even with the upper energy draw and marginally decrease noise ranges, the Zotac 5080 card manages decrease temperatures than the 5080 FE. Contemplating the enormity of the Zotac card, that is what we have to see. The 4-degree discount in GPU and 7-8 diploma discount in reminiscence thermals provides the Zotac Strong a bonus, though not in dimension, however the dimension is working in its favor.
Frequency
This chart exhibits the frequency over the take a look at go. The FE card plotted round 2650 to 2680 MHz on common, holding comparatively steady underneath this take a look at workload.
For reference, the 5090 has a decrease and spikier clock. The configuration is way bigger and the 5090 makes up for the distinction in different methods.
Including the Zotac 5080 strong to the chart, its clock is increased than the NVIDIA FE mannequin, touchdown at 2790 to 2842 MHz. It is a fairly vital uplift. We’ll take a look at that in some efficiency eventualities momentarily to see what it really does.
Noise Frequency Spectrum
The subsequent chart is produced utilizing our hemi-anechoic chamber that we constructed with help from our Patreon backers and our supporters on retailer.gamersnexus.internet, which permits us to isolate noise and guarantee a like-for-like testing surroundings day-to-day.
This chart exhibits the 5090 Founders Version and the Zotac 5080 Strong. The 5080 Founders Version is usually equal to the 5090 Founders Version, with the exception that the fan curve runs barely slower and so the noise is diminished by about 1 dBA in our workloads.
The Zotac Strong doesn’t encounter the identical 180 Hz spike we noticed within the 5090 and 5080 FE coolers, however does have its personal spike round 433 Hz. The curve usually follows the identical path, with marginally increased noise ranges within the 1000 Hz to 1600 Hz vary, however decrease noise ranges in most different locations. The Zotac Strong total manages to maintain its noise ranges down and avoids being obnoxious. It’s making use of its dimension.
VBIOS Comparability – Frequency
It is a fast VBIOS comparability for the Zotac 5080 Strong. Between the 2 VBIOS choices, frequency is sort of fully equivalent. There is no such thing as a significant distinction.
VBIOS Comparability – Thermals
For thermals, the silent VBIOS runs about 3-4 levels hotter on the GPU from its diminished fan speeds. The followers run about 4-6 share factors slower than the default VBIOS. The reminiscence temperature climbs about 3 levels. There’s not a big effect to thermals from the VBIOS change and the followers don’t actually change so much both.
Zotac RTX 5080 Strong Gaming Benchmarks
Resident Evil 4 – 4K
In Resident Evil 4 at 4K, the RTX 5080 Strong ran at 128 FPS AVG and led the 5080 FE by 4.2%. That’s not a nasty uplift, but it surely’s unhealthy for nearly $300 extra, although. Lows are inside normal variance and benefitted equally.
Resident Evil 4 – 1440p
At 1440p, the 5080 Strong held 237 FPS AVG towards the 5080 FE’s 224, which is a 6% lead. That’s an enormous bounce throughout the similar GPU mannequin. Once more, the value isn’t justified, however at the very least we’re seeing an impression from the pre-overclock by Zotac.
Black Fable: Wukong – 4K RT
In Black Fable: Wukong at 4K and ray traced with upscaling, we noticed the RTX 5080 Strong at 60 FPS to the FE’s 58.6. That’s a 2.6% enchancment over the FE mannequin.
Black Fable: Wukong – 1080p RT
At 1080p and with RT with upscaling, the Strong ran at 128 FPS AVG to the FE’s 122. That’s a 5.5% enchancment over the FE mannequin.
Ultimate Fantasy XIV – 4K
In Ultimate Fantasy 14 Dawntrail at 4K, we noticed the 5080 Strong at 117.5 FPS to the FE’s 112.4, a 4.5% uplift. This development repeated throughout the opposite video games we examined. It’s constant, so we’ll cease right here with the sport benchmarks because it tells the identical story. Briefly, it’s usually about 3-6% higher.
Overclocking – Metal Nomad
Overclocking has some bugs on the 50-series proper now. We haven’t dug an excessive amount of into this bug, but it surely seems as if the voltage offset slider has a problem with the 50-series at current and reduces GPU clocks when used. We ended up setting it to 0 as an alternative.
This fast desk exhibits the overclock stepping with 3D Mark Metal Nomad. From inventory, we have been in a position to maintain an offset of 700 MHz core, which is big, and not using a reminiscence offset, touchdown the consequence at 8160 factors. The uplift from inventory was an insane 28%. This was not replicated in real-world use circumstances so examine your expectations. Including reminiscence clocks launched instability with out dropping the core offset to 650 so we did that.
Sadly, we weren’t ready to make use of the 700 MHz offset with the reminiscence offset. We additionally have been unable to search out stability from these clocks in any gaming use case, so sadly, it was purely artificial. That is largely attention-grabbing from a aggressive overclocking standpoint.
Overclocking – FFXIV 4K
The subsequent testing was solely carried out for a efficiency examine. We didn’t burn this in for stability, so we need to actually closely emphasize that this overclock will not be steady in all video games we take a look at. It was solely steady in Ultimate Fantasy XIV: Dawntrail at 4K. You’d must spend time tuning it right down to dial it in, however we needed to current what we discovered up to now.
The inventory 5080 FE ran at 112 FPS AVG. The 5080 Strong, out of the field, ran at 117.5 FPS with none background purposes. We noticed efficiency degradation once we started working Zotac’s utility within the background along with altering the clocks and fan speeds, so simply growing the ability offset and making use of as much as a 200 MHz core offset resulted in efficiency equal to or worse than inventory. We have been in a position to run the Ultimate Fantasy benchmark with stability as much as a 500 MHz core offset and 1200 reminiscence offset; nonetheless, we’re not sure if there are any invisible background points with this reminiscence offset particularly out of this sport.
The tip consequence was a 125.7 FPS AVG, which led the inventory Zotac Strong results of 117.5 FPS AVG by 7%. That’s not a nasty uplift but it surely’s not that thrilling. The lead over the FE mannequin is sort of 12%, which is extra significant.
General, that’s an honest quantity of OC headroom from the bottom FE consequence, whereas the 7% uplift is typical for latest generations. In no real-world case have been we in a position to replicate the Metal Nomad uplift.
Overclock Frequency Outcomes
Lastly, right here’s the frequency chart in Ultimate Fantasy. This isn’t akin to the sooner charts for frequency. Out of the field, the cardboard ran at 2625 MHz. Reminiscence ran at 1875 MHz, however remember that there’s a multiplying impact for GDDR.
The core after a 500 MHz offset ran at 3120 MHz, which is sort of 1-to-1. The reminiscence after offset ran at 2025 MHz. That is about right and what we’d anticipate after multiplying the numbers for GDDR efficient speeds.
As an essential notice right here, the sort of testing largely seems on the impression from the ability % slider offset. Broadly talking, GPU variance from the “silicon lottery” has extra complete impression than any explicit accomplice mannequin outdoors of its energy boosting headroom (and the tremendous high-end fashions typically being binned, however that is uncommon on something however flagships).
Zotac RTX 5080 Strong Conclusion
The Zotac RTX 5080 Strong is constructed nicely total. We didn’t see any large pink flags with this card aside from its worth. Should you don’t care about that and also you simply need a 5080, this card is ok, once more, aside from its worth. We didn’t have any main complaints with its thermals, meeting, or acoustics.
The thermals, specifically, are a bit of bit higher than the Founder’s Version card, however not a lot better as they in all probability must be given the scale of the cardboard. The reminiscence was improved an honest quantity, nonetheless, being roughly 7 to 9 levels cooler.
Efficiency is roughly 2-5% higher out of the field than the Founder’s Version card.
Previously, we discovered Zotac’s MOSFETs weren’t contacting the thermal pads for the heatsink, however that, happily, wasn’t the case right here.
General, there was nothing massively detrimental right here other than the worth as $1,000 for a 5080 is already very questionable. It’s laborious for us to check the thermal efficiency once we solely have this accomplice mannequin. We haven’t been in a position to get any others but, however that’s one thing we’d prefer to dive deeper into offered we will get extra playing cards in.
