    GPU Relative Performance Chart - Updated for RTX 3060

    Posted: 01 Mar 2021 06:24 AM PST

    EDIT: https://i.redd.it/4rwxkzv0cgk61.png - hopefully less headache inducing...

    Last time I posted this there was a lot of negativity for some reason, nevertheless quite a lot of people thought it was helpful so I will post this as an update to which hopefully you may agree.

    To stave off any confusion/hate I'll explain upfront that the methodology is to collate a number of benchmarks from various reviewers for each GPU, usually around 5 or 6. And within those however many games are tested. Figures are all based on average fps relative to a 3090 being the top. Since that's defined as '100%' is why it appears missing. In certain cases a 6900XT will be faster than a 3090 even though it's ON AVERAGE slower that's why the graph goes beyond 100%. For the top GPU's 4K is the resolution and it drops down to 1440p when those GPU's cannot output 60fps 'regularly' at 4K and so on and so forth down to 1080p at the low end. I have intentionally NOT used candlestick style markers because I am assuming roughly speaking a normal distribution so there is nothing that a candlestick would help with. Similarly the absolute numbers are intentionally missing because the intent is not to gauge whether one GPU is ranked as 43.5% and one at 44.7% because in real life those are functionally the same. The intent is to give a representative idea of where each GPU compares with each other. "Is X similar performance to Y or Z?" that kind of thing. Obviously this is rasterization only, no RT and no DLSS or SAM and that type of stuff. With the older GPU's the data is less reliable for obvious reasons.

    EDIT:

    I've added in some cost data to give an idea of value: https://i.redd.it/bo1iy1pbllk61.png

    That's inflation adjusted cost vs 3090 against relative performance to 3090. I guess what's important is the blue dots wich is just 'rel perf/rel inf adj cost'

    EVGA 3080 XC3 Ultra Gaming + Hybrid Cooler Review

    Posted: 01 Mar 2021 10:49 AM PST

    I was lucky (?) enough to purchase a EVGA 3080 XC3 Ultra Gaming from BestBuy.com in mid-January of 2021. In this post, I'd like to post my impressions of the card, the improvements I've noticed in my favorite titles, and my review of the hybrid kit that I installed.

    My Build: 5600X / 3080 XC3 Ultra Hybrid / 32GB / x570 Tomahawk / NH-D15 / Meshify C. All games are played at Ultra settings on a 144hz UWQHD monitor.

    Initial 3080 XC3 Impressions:

    Performance: 15-20% improvement from my old card (5700xt). I was a bit disappointed that I only went from around 50fps -> 60fps in my favorite game, RDR2. However, as I'll cover in the later sections of the review, I was hitting thermal throttling limits and losing performance with the stock cooler. Older / less intensive games such as AOE2 played great at my monitor's max 144fps.

    Thermals & Acoustics:

    With the stock cooler, temps and noise were BAD. Unusable really - temps were throttling at the 83C limit with stock power usage and no OC - I had to undervolt my card to 90% power limit just to get temps to sit right below 80C and fans still going at basically max speeds. I have a Meshify C with good airflow - my old card never went above 60C under load. I also tested with side panels off and fan curves maxed out (temps were still bad). For this reason, and given what I paid (over $800), I would not recommend the XC3 Ultra - the stock cooler just isn't good enough. You may be able to play around with re-applying thermal paste (my stock application had a few places where the paste wasn't completely covering the die, so I presume that I just got an especially bad unit) to get better results here, but the fact remains that the stock cooler just isn't up to the task of cooling this card. Other reviews I have encountered have had similar sentiments.

    Hybrid Kit Review:

    Once I realized that the stock cooler wasn't going to work, instead of RMA'ing / returning I decided to spend an extra ~$110 on a hybrid cooler directly from EVGA. After a relatively easy install (use YT guides - they're very helpful where the included instructions become unclear, a quick fan upgrade to the radiator, and a BIOS update to the hybrid bios (you must do this to get proper fan controls and RGB), my card now idles at ~20C and barely hits 50C under load. Although this is great, I can't help but feel like I've overshot the cooling performance I needed for this card. At this point, I wish I had been able to purchased the FTW3, which can draw extra power. Having said all of that, I noticed an immediate performance boost due to the improved cooling, reaching almost 80fps on RDR2 and 16k total score on 3DMark with the following stable overclock: 107% / +150mhz / +1000mhz (power/clock/memory).

    Overall Thoughts:

    The following recommendations are assuming you can purchase a 3080 at post-tariff MSRP prices. I understand that this isn't the case currently, but hopefully it will be the case in the future.

    3080 XC3 Ultra Stock - Would not recommend - stock cooler provides inadequate performance for the card, causing throttling.

    XC3 Hybrid Kit - Would recommend only if you're unable to secure a better card or really want to go water cooled. Having said that, if you're able to purchase the hybrid pre-assembled from EVGA, I would say that's a good deal (it's the same price as the XC3 Ultra with stock cooler, I believe).
