My current HTPC has an nVidia GeForce GTX 1050Ti 4Gb with which I am able to upscale all content to 1080p with fairly high quality settings, اور میں بھی ہوں (صرف) able to playback 8k 60fps content downscaled to 1080p. However, I have long wondered what the benefits of a more powerful card might be on the ability to use higher settings. افسوس کی بات ہے, no-one seems to provide any benchmarks for madvr, تو کارڈ کا موازنہ کیسے کیا جاسکتا ہے?
After much searching, it seems that the strongest indicator of madvr performance is the shader performance of a card. This is effectively measured in FLOPS. There are some limitations to this as a doubling of shader performance doesn’t necesarily mean a halving of render time so the relationship isn’t necesarily linear, but once other factors (e.g. memory quantity and speed) برابر ہیں, the shader performance will be a good guide to the performance of a card.
It is highly recommended to get a GPU with at least 4Gb of VRAM for madvr. Assuming a new card is being obtained, میموری کم از کم GDDR5 ہونے کا امکان ہے, اور اچھی طرح سے GDDR6 ہوسکتا ہے. In these circumstances the shader performance is a useful guide.
I also used a few specific pieces of information to compare different benchmarks to see which type appeared to be the best fit. معلومات کا ایک ٹکڑا جو میں نے اٹھایا وہ ہے میری 1050ٹیڈی ریڈین آر ایکس سے تیز ہے 570 in madvr which is not reflected in lots of GPU compute benchmarks which suggests these are not a good type of benchmark to use.
Another direct comparison suggests that the 1060Ti is faster in madvr than the RX580 so this should also be reflected in any benchmarks used, جو ان میں سے بیشتر کو مسترد کرتا ہے! In the same thread there is a suggestion that the Radeon RX 5700 XT is similar in performance to a GeForce RTX 2070 Super
Some other facts from the doom9 forums
- AMD RX480 GTX970 سے قدرے تیز ہے
- GTX1070 آس پاس ہے 30% RX480 کے مقابلے میں تیز ہے
As I wasn’t able to find any benchmark that matched these data points, instead I’ve started by looking at all the cards available in the £100 — £200 bracket which are…
- جی ٹی ایکس 1660 £ 195
- RX590 £ 190
- RX5500 XT £ 160
- جی ٹی ایکس 1650 سپر £ 150
- RX580 £ 145
- جی ٹی ایکس 1050Ti £ 130
Is there a surprising winner, or does the price predict the performance?
The info I can find suggests that the GTX 1650 (سپر نہیں) is کے ارد گرد 25% تیز تر than the GTX 1050Ti in madvr, اور 1650 سپر ایک بار پھر تیز ہے (more cuda cores and a higher clock speed). یہ بھی ظاہر ہوتا ہے کہ RX5700 XT ہے تھوڑا تیز جی ٹی ایکس سے زیادہ 1080 اور وہ RX5700 (XT نہیں) is similar to a GTX 1070.
After lots of searching to compare these cards I found a very useful post on reddit which ranks the nVidia cards approximately. These rankings (unsurprisingly) do follow the price of the nVidia cards.
- جی ٹی ایکس 1050 / 1050 ٹی
- جی ٹی ایکس 1650
- GTX 1650 Super
- جی ٹی ایکس 1060
- جی ٹی ایکس 1070/1660 / 1660 سپر / 1660 ٹی
- جی ٹی ایکس 1080 / RX 2060
- GTX 1080Ti / RTX 2070
The better cards (towards the bottom) tend to be beyond the price range. میں ایک جی ٹی ایکس دیکھ سکتا ہوں 1070 ای بے پر £ 230 کے لئے جو ایک نئے GTX سے زیادہ ہے 1660 لہذا دوسرے ہاتھ کے اختیارات مدد کرنے کے لئے ظاہر نہیں ہوتے ہیں. ای بے پر تقریبا£ £ 170 میں 6 جی بی جی ٹی ایکس 1060 بھی ہیں (3Gb کافی نہیں ہے, 4Gb is a minimum really so be careful with these) — but are they really £20 better than a new GTX 1650 Super?
It sounds like the AMD Polaris generation cards weren’t good performers in madvr. This has apparently changed with Navi, however there have been driver issues with Navi so most people still recommend nVidia cards for madvr. On top of this it is rumoured that future versions of madvr may make use of the nVidia turing architecture, but these rumours are at least a year old with nothing to show so far. If they ever come true it may be that AMD’s “ray-tracing” compatible cards may be just as well suited too.
I have a suspicion that the RX 5500 XT اچھی قیمت کا سودا ہوسکتا ہے کیونکہ یہ جی ٹی ایکس کی پیش کش کرسکتا ہے 1660 like performance in madvr, £ 35 کم کے لئے, but I can’t find concrete evidence or a direct comparison.
Thanks for the precious information
Doesn’t the 1070 ہے 6+ tflops whereas the 1660 صرف ہے 5 tflops? Wouldn’t this make the 1070 better for madvr, especially when the 1070 comes with 8gb of memory?
Possibly so, altho my guess is that the difference isn’t big enough to enable any additional settings in madvr so may be irrelevant. The tflops score doesn’t appear to perfectly predict madvr performance. The only way to know for sure would be to test both but I haven’t found anywhere doing direct comparisons of cards in madvr.
